How do you solve $\frac{x}{- 3} + 3 = 7$ $x/-3+3=7$ ?

1 Answer

$x = - 12$ $x = -12$

Explanation:

Given $\frac{x}{- 3} + 3 = 7$ $x/(-3) + 3 = 7$

Clear the fraction by multiplying all terms (on both sides) by $(- 3)$ $(-3)$
$XXXX$ $color(white)("XXXX")$ $x - 9 = - 21$ $x -9 = -21$
Add $9$ $9$ to both sides
$XXXX$ $color(white)("XXXX")$ $x = - 12$ $x = -12$
