Answer:
I believe x = 2.
Use distributive prop. to get rid of parentheses:
3x-12=-4x+2
Move the -12 over to the other side. Since everything that goes to the other side changes signs, the "-" sign will change to a "+" sign. Move the -4x to the other side as well. Remember to change the sign!
3x + 4x = 2 + 12
Now combine like terms:
7x = 14
To get the x fully isolated, we need to divide both sides by 7 so we can get rid of the 7.
7x/7 = 14/7
x = 2
Hope this helped! :)
