You use PEMDAS (Parenthesis, exponent, multiplying or dividing, addition or subtraction)
3x - 13 = 7(x+2) - 4(x-7)
3x - 13 = 7x + 14 - 4x + 28
3x - 13 = 3x + 42
-13 = 42 <--- Not True
There is no solution since the left and right sides aren't equal

7x+14-4x+28. 3x+42. 3x-13=3x+42. Not equal x is 0
