-6x-6 -or- -6(x+1)
10x + 7 = 4x + 49 6x + 7 = 49 6x = 42 x = 6
6 + x - 10x = 11 - 4x 6 - 9x = 11 - 4x add 9x to both sides: 6 = 11 + 5x subtract 11 from both sides: -5 = 5x divide both sides by 5: -1 = x
-31 - 10x = 41 - 4x In algebra what you do to one side of the equation you do the the same as the other First add 31 to both sides -10x = 72 -4x then add 4x to both sides -6x = 72 divide both sides by -6 x = -12
