8. Solve the equation.
3x – 10 = -x - 2
A 12
B 8
C 2
D4

c. 2

Step-by-step explanation:

The first step in solving these kinds of equations is to combine the like terms. You always start with the variable, which in this case is x. Always move the variable with the lower coefficient.

3x - 10 = -x - 2.

3x + x = 4x. (when it is a negative, you add it to the other side. When it is a positive, you subtract. In this case it is negative so we add. )

4x - 10 = -2.

Now, you want to move whichever number is on the side of the equals sign with the variable, which in this case is ten. Because it is negative, we are adding it to -2.

-2 + 10 = 8.

4x = 8.

Your last step is to divide 8 by the coefficient of x, which is 4. This leaves us with x = 2, which is our answer. :)
