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
The value of x is 11/2
10x - 25 = 4x + 510x - 4x = 25 + 56x = 30x = 5
10x + 17 = 4x - 16x = -18x = -3

-31 - 10x = 41 - 4x-31 + 31 - 10x = 41 + 31 - 4x- 10x = 72 - 4x-10x + 4x = 72 - 4x + 4x-6x = 72-6x ÷ -6 = 72 ÷ -6x = -12Check Your Solution:x = -12-31 - 10x = 41 - 4x-31 - 10(-12) = 41 - 4(-12)-31 + 120 = 41 + 48120 - 31 = 41 + 4889 = 41 + 4889 = 89
