Answer:
x = 2.
Step-by-step explanation:
Start by distributing the 3 to what is in the parentheses.
3 times 2x = 6x.
3 times -3 = -9.
So now you have:
6x - 9 = 7 - 2x.
You want to get the x variables on one side.
So add the 2x to both sides.
8x - 9 = 7.
You want to get x by itself.
So add 9 to both sides.
8x = 16.
x = 2.
