what would x + 4 + x = -20 be?
820839
x+4+x= -20\nFirst collect like terms.\n2x+4= -20\nGet rid of the 4. Subtract 4 to both sides.\n2x+4-4= -20-4\n2x= -24\nIsolate the x. Divide both sides by 2.\n2x/2= -24/2\nx= -12

20 + x = -4x +15\n20 + x + 4x = -4x + 4x +15 (note I wanted to get x on the left of the = sign so I added 4x on both sides, if you only do it on one side, the equation will be unequal).\n20+ 5x = 15\n20- 20 + 5x = 15 - 20\n5x = -5\n5x/5 = -5/5\nx=-1\n\n5 = 5(x-1) + 3 - 4x\n5 = 5x -5 +3 -4x\n5= x - 2\n7 = x\n\n-5 +6 - 8x = -150\n1 - 8x = -150\n1 -1 - 8x = -150 -1 \n-8x = -150 -1 \n-8x = -151\n-8x/-8 = -151/-8\nx =151/8\n\nthe last one is similar to the first. just remember you need to solve for x and get x onto one side of the equation. Good luck!

20 divided by 4 equals 5.

(5)(5)-2(5)(-4)+(-4)(-4)\n=25-(-40)+(16)\n=25+40+16\n=81\n\nDon't forget that (-)(-)=(+) and (-)(+)=(-).\n\nGood luck!

so that x=4+ or - 3i\nthen transpose 4 to left\nx-4=+/- 3i square both sides\nthat's x^2-8x+16=-9\ntranspose -9 to left side\nx^2-8x+25=0

outside, put 4i  inside put 1  0  8  26i  -20\n\n4i)..1....0....8....26i....-20.\n.....1...4i...-8....-6i......4     \n\n(remember i^2 = -1)\n\n\n4i because 4i times 1 + 0 = 4i\n-8 because 4i times 4i is 16i^2 which is -16, plus 8 = -8\n-6i because 4i times -8 is -32i plus 26i = -6i\n4 because 4i times -6i is -24i^2 which is 24 minus 20 is 4\n\nSo the answer is x^3 + 4ix^2 - 8x - 6i, remainder 4

For all those people giving the answer\n4/4+4*4 = 20\nyou need to learn the order of operations!!\nIn this problem the first operation performed is multiplication or division in the order in which they appear.\nFor the problem division is done first.\n4/4 = 1\nThus the problem becomes\n1+4*4  Now there is still multiplication in the probem so that has to be done before the addition.\nHence, 4*4 = 16\nThus, the problem is now\n1 + 16\n= 17 and does not equal 20.\nIf there were parentheses (other people have already done this), then you could say\n(4/4+4)*4 = 20 because then you could add the 4 and the 1 together first because operations inside parentheses are performed before the other operations.\nSo you have\n(4/4+4)*4\n= (1+4)*4\n= 5*4\n= 20\nHowever, I'm not sure parentheses are allowed to be included because now there are 5 symbols being used instead of 3.\nI would use the symbols !, / and -\nThe exclamation point means factorial.\n4!4/4-4   First evaluate 4! (4! = 4*3*2*1 = 24) and then multiply by 4\n96/4-4   Now 96/4 = 24\n=24-4\n=20

It'sa simple aquation...\n\nx-4/4-x = x-1-x = x-x-1 = 0-1 = -1

4*4+4+Sqrt(4) = 22, \n\nthis is 4*4 = 16\nplus 4 = 20\nplus the square root of 4, which is 2 = 22\n\nusing only the number four!

x/ -4 + 5 = 1\nsubtract 5 from both sides\nx/ -4 = -4\nthen multiply both sides by -4\nx = 16

-4x - 20= 8 (make an equation)\nx + 5= -2 (divide both sides by -4)\nx= -7 (subtract 5 from both sides)\n\nThe answer: -7

4, 0, -2, -2, 0\n\nFigure it out! Don't be lazy!

let's say u=4^x\nso the equation becomes:\nu^2-20u+64=0\n(u-16)(u-4)=0\nu=16 or u=4\n\nsubstitute 4^x in to get:\n4^x=16 or 4^x=4\n\nthus, x=2 or x=1

x + 3 >  8 ==> x >  8 - 3  ==> x > 5\nx - 4 < -2 ==> x < -2 + 4 ==> x < 2\n\nAnswer... not possible.
