It is: -4x-10x = -14x
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
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
