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

1 Answer

If identical standard arithmetic operations (other than division by zero) are performed on both sides of an equation, the equation remains valid. ( $x = 1$ $x=1$ )

Explanation:

$3 x + 3 = 6$ $3x+3 = 6$
$XXXX$ $color(white)("XXXX")$ Subtract 3 from both sides
$3 x = 3$ $3x = 3$
$XXXX$ $color(white)("XXXX")$ Divide both sides by 3
$x = 1$ $x=1$
