Answer 4

solve for x first im guessing

Answer 5

For the given equation, the two sides are equal to one another. So that means they are equal to the same variable, say y.

So

y = x+4
y = 3x + 12

notice if we were to start with y = 3x + 12 and replace y with x+4 (valid because y = x+4), we'd get the original equation back again.
