First write out the equation
[tex] \frac{-7}{3} x-3=-52[/tex]
Add three to both sides to cancel out
[tex] \frac{-7}{3} x=-49[/tex]
Multiply both sides by the reciprocal of the fraction being multiplied by x
[tex]( \frac{-3}{7} ) \frac{-7}{3} x=-49( \frac{-3}{7} ) [/tex]
Cancel out the fractions and you're left with positive 21
[tex]x=21[/tex]
