4n/5=-8       what is x?
481027
As stated by katie, there is no " x ". However, check this out. 4n/5 * 5 = -8 * 5\n     4n = -40\n      n = -10 \n\nPretty simple as you can see. Good luck !

The general approach is to move the x's to one side of the equation and the numbers to the other side, then solve for x. In your example:\n\n5x - 6 = 4x -+ 8\nFirst step: move 4x to left side. Since you can subtract the same amount from both sides of an equation the detailed step looks like this:\n5x - 6 - 4x = 4x + 8 - 4x\nor, in short form,\n5x - 4x - 6 = 8\n\nThen, move the 6 to the other side by adding 6 to both sides:\n5x - 4x - 6 + 6 = 8 + 6\nor, in short form:\n5x - 4x = 8 + 6\n\nThen, reduce both sides of the equation:\nx = 14\n\nHope this helps!

x = [-(-4) +/- root((-4)^2 - 4x1x(-5))]/2x1\n  = (4 +/- 6)/2\n  = 5 or -1

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

Multiply both sides by 2x so it looks like this -5/1=30*2x which is the same as -5=60x. The divide both sides by the 60 to isolate it. And ur answer comes out to be x= -5/60

(n/4 + 11) - 11 = 31-11 (Sub. 11 from both sides.)\nn/4 * 4 = (31-11) *4 (Mult. both sides by 4\nn = (20) *4\nn=80

There needs to be an "x" there somewhere.  If it were\n-4x + 7 > 15, you'd have \n-4x > 8\n  x < -2 (because you switch the sign when you divide by a negative)

x = 6\n\n8x + 5 = 4x + 29   (subtract 5 from both sides)\n8x = 4x + 24         (subract 4x from both sies\n4x = 24                 (divide both sides by 4)\nx = 6

nope \n5x+5y\n\nthe 4y and -4y cancel each other out

x is anything less than 1.\n4 x1=4 so 1 cannot be the answer (unless the < had a line underneath it)\n4x0=0 which is less than 4\n4x -2= -8

Do not write x = 0 because think about it\n\nif x = 0, then that would mean that |0+4| + 4 = 0\n\nthat means 8 = 0... is that true? NO!\n\nSince it is imposible for |x - 4| to equal -4 (since absolute value is ALWAYS possitive or 0) there is no solution =)
