This is an example of why we always get everything on the left side, then factor to make the product zero:
(x+4)(x12) = 5x
x^2  8x  48 = 5x
x^2  13x  48 = 0
(x16)(x+3) = 0
Now we have a zero product. That means that if any of the factors is zero, then the product is also zero.
So, x = 3 or 16
Now do the same steps with the second equation
