  3. Calculate: -(4)/(3) * (n-6)=12

Expression: $-\frac{ 4 }{ 3 } \times \left( n-6 \right)=12$

Multiply both sides of the equation by $\frac{ 3 }{ 4 }$

$-\left( n-6 \right)=9$

When there is a $-$ in front of an expression in parentheses, change the sign of each term of the expression and remove the parentheses

$-n+6=9$

Move the constant to the right-hand side and change its sign

$-n=9-6$

Subtract the numbers

$-n=3$

Change the signs on both sides of the equation

$n=-3$
