-3x+ 7 = -2
what is x?

x=3

Step-by-step explanation:

The first thing that I did to solve this equation was do the opposite of the positive 7 so I subtracted 7 on both sides.

-3x + 7 = -2

      -7  = -7

-3x       = -9

Now we have the equation of -3x = -9. From there we will do the reciprocal of -3x so we will divide it on both sides.

-3x/-3 = -9/-3

x         =   3

And now we have the answer of x=3.
