Answer:
x=3
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.
