Question 522614
12*x+16*x-14*x=14*x+13*x+52 
The problem there has been giving me a problem, trying to understand why the 
answer is -4 ?
**
12*x+16*x-14*x=14*x+13*x+52
rewrite the equation in normal form
12x+16x-14x=14x+13x+52
move all the x-terms to one side on the left
12x+16x-14x-14x-13x=52
add the x's
-13x=52
x=52/-13=-4
