Question

$$\frac { 11 } { 2 } - \frac { 3 n } { 4 } + \frac { 5 n } { 6 } = 21$$

Solve for n

$n=186$

Steps for Solving Linear Equation

Multiply both sides of the equation by $12$, the least common multiple of $2,4,6$.

$$66-3\times 3n+2\times 5n=252$$

Multiply $-3$ and $3$ to get $-9$.

$$66-9n+2\times 5n=252$$

Multiply $2$ and $5$ to get $10$.

$$66-9n+10n=252$$

Combine $-9n$ and $10n$ to get $n$.

$$66+n=252$$

Subtract $66$ from both sides.

$$n=252-66$$

Subtract $66$ from $252$ to get $186$.

$$n=186$$
