Solve for n -28+8n=5n+3n-21

$- 28 + 8 n = 5 n + 3 n - 21$

Since $n$ is on the right side of the equation, switch the sides so it is on the left side of the equation.

$5 n + 3 n - 21 = - 28 + 8 n$

Add $5 n$ and $3 n$ .

$8 n - 21 = - 28 + 8 n$

Move all terms containing $n$ to the left side of the equation.

Subtract $8 n$ from both sides of the equation.

$8 n - 21 - 8 n = - 28$

Combine the opposite terms in $8 n - 21 - 8 n$ .

Subtract $8 n$ from $8 n$ .

$0 - 21 = - 28$

Subtract $21$ from $0$ .

$- 21 = - 28$

Since $- 21 \neq - 28$ , there are no solutions.
