# How do you solve 3x+3=6?

If identical standard arithmetic operations (other than division by zero) are performed on both sides of an equation, the equation remains valid. ($x = 1$)
$3 x + 3 = 6$
$\textcolor{w h i t e}{\text{XXXX}}$Subtract 3 from both sides
$3 x = 3$
$\textcolor{w h i t e}{\text{XXXX}}$Divide both sides by 3
$x = 1$
