I can not figure out the next step can someone help
(x+3)*4+(x-3)*3=-5x
4x+12+3x-9=-5x
7x-3=-5x
From
4x+12+3x-9=-5x
You can start to isolate the variable, i.e. gather all terms containing the variable to the left of the equals sign, and numbers and constants to the right.
The next step could be:
7x+3 +5x-3 = -5x +5x-3
12x = -3
x=-1/4
