-4
The steps in solving the equation for x are necessary to isolate the variable x and find its value. The first step is to use the distributive property to separate the 4x and 3 terms. The second step is to combine like terms on the left side of the equation. The third step is to add the opposite of the 6 to both sides of the equation. The fourth step is to divide both sides of the equation by -8 to isolate the x variable. The fifth step is to find the value of x, which is -4.
What reasons can be given for the steps in solving the equation for x ?
-2(4x + 3) = 26
-2(4x) + -2(3) = 26
-8x - 6 = 26
-8x - 6 + 6 = 26 + 6
-8x = 32
-8x/-8 = 32/-8
x =

(your math teacher would expect to see these steps)
-2(4x + 3) = 26
-8x - 6 = 26
-8x = 32
x = -4
