Solve 168=2(n+10)*4+n*10

$$168 = 2 ( n + 10 ) \times 4 + n \times 10$$

Solve for n

$$n = \frac{44}{9} = 4\frac{8}{9} \approx 4.888888889$$

Steps for Solving Linear Equation

Multiply 2 and 4 to get 8.

$$168=8\left(n+10\right)+n\times 10$$

Use the distributive property to multiply 8 by n+10.

$$168=8n+80+n\times 10$$

Combine 8n and n\times 10 to get 18n.

$$168=18n+80$$

Swap sides so that all variable terms are on the left hand side.

$$18n+80=168$$

Subtract 80 from both sides.

$$18n=168-80$$

Subtract 80 from 168 to get 88.

$$18n=88$$

Divide both sides by 18.

$$n=\frac{88}{18}$$

Reduce the fraction \frac{88}{18} to lowest terms by extracting and canceling out 2.

$$n=\frac{44}{9}$$
