Question:

Solve for x:
3(x + 1) = 5(x − 2) + 7.

A 3
explanation

Begin by distributing the 3 and the 5 through their respective parentheses, then combine like terms on each side of the equal sign:
3(x + 1) = 5(x − 2) + 7
3x + 3 = 5x − 10 + 7
3x + 3 = 5x − 3
3x + 6 = 5x
6 = 2x
3 = x

Pretty good for learning basic stuff. Just wish the equation would change up so you don't just remember the answer.
