-14x
As an algebraic expression it is 10x
Ok so your equation reads like this (I assume you forgot the +): 3 - 4x = 10x +10 The goal is to get the x's on one side and the other numbers on the other. It doesnt matter which side has which, so I will move the numbers to the right and the x's to the left. So first subtract 3 from both sides: 3 - 3 - 4x = 10x + 10 - 3 -4x = 10x + 7 Now subtract 10x from both sides. -4x - 10x = 10x - 10x + 7 -14x = 7 Now that we have like terms on both sides, all you need to do is divide both sides by -14 to solve for x. -14x / -14 = 7 / -14 x = -1 / 2
If you mean: 4x-14x+7 then the expression can be simplified to 7-10x

-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

10x + 17 = 4x - 16x = -18x = -3

10x - 25 = 4x + 510x - 4x = 25 + 56x = 30x = 5
4x-3+6x+3 4x+6x=10x -3+3=0 10x is the answer!
4x(10x + 1)
-14x
