Hey there!
This is a pretty long equation, but don't let it confuse you- it's full of like terms.
Let's clean up the right side by adding the 4x and the 2x:
6x+2=3x-7
We can subtract 3x from both sides:
3x + 2 = -7
Subtract two to both sides to get:
3x = -9
Finally, divide both sides by 3 to get:
x = -3
Hopefully this helps!
