Is it possible to have 2 equal signs in a problem?\nI am only in algebra but I haven't seen one like that before.\nSorry I couldn't help.

[8+(2*4)]*3 =48 =16*3=30+18=48, just this first expression none of the others

20 divided by 4 equals 5.

No, you add exponents when you multiply, so you would have\n5*(-4)r^(2-3) = \n-20r^-1 = -20/r

Yes, I can:\n4! + 4 \n=\n(4 x 3 x 2 x 1) + 4 = 28\n\n(BTW, 4squared + 4squared = 32)

22+2 = 24\n8+8+8 = 24\n3^3-3 = 24

The trick is to substitute a known true equation. I used 2+3=5, but any true equation will work.\n\nSubstitututing in the first equation you get\n4(2) - 3(2) + 4(3) - 3(3) = 4(5) - 3(5)\n\nwhich is 8 - 6 + 12 - 9 = 20 - 15\n\nor 5 = 5.\n\n\nIn the second equation you get\n4(2) + 4(3) - 4(5) = 3(2) + 3(3) - 3(5)\n\nwhich is 8 + 12 - 20 = 6 + 9 -15\n\nor 0 = 0.\n\n\nHence, a + b - c = 0.  In the next equation, you are dividing by zero, which is not permissible in math.  If a +  b - c had not been equal to zero, then this would have been possible.

Any small square of four numbers totals 20

The number is 4(x+3), or 4x+12

20 + x = -4x + 15\n5x = -5\nx = -1\n\n5 = 5(x - 1) + 3 - 4x\n5 = 5x - 5 + 3 - 4x\n5 = x - 2\nx = 3\n\n-5 + 6 - 8x = -150\n5 - 6 + 8x = 150\n-1 + 8x = 150\n8x = 149\nx = 149/8

5/7 - 3/4 = (4*5 - 7*3)/28 = (20-21)/28= -1/28\nSo the answer is: y to the (-1/28).

5x-3 = 3x +37\n2x=40\nx=20\n\nmuch better this time.  still kinda a dumb question.

-3x - 12x - 3 = 4 -12x + 20\n-15x - 3 = -12x + 24\n-27 = 3x\nx = -9

two ways are .4 and 20/50

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
