Solve 2m+m=9quadN

$$2 m + m = 9 \quad N$$

Solve for N

$$N=\frac{m}{3}$$

Steps for Solving Linear Equation

Combine 2m and m to get 3m.

$$3m=9N$$

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

$$9N=3m$$

Divide both sides by 9.

$$\frac{9N}{9}=\frac{3m}{9}$$

Dividing by 9 undoes the multiplication by 9.

$$N=\frac{3m}{9}$$

Divide 3m by 9.

$$N=\frac{m}{3}$$

Solve for m

$$m=3N$$

Steps for Solving Linear Equation

Combine 2m and m to get 3m.

$$3m=9N$$

Divide both sides by 3.

$$\frac{3m}{3}=\frac{9N}{3}$$

Dividing by 3 undoes the multiplication by 3.

$$m=\frac{9N}{3}$$

Divide 9N by 3.

$$m=3N$$
