Solve A=5(10x+8)

$$A = 5 ( 10 x + 8 )$$

Solve for x

$$x=\frac{A-40}{50}$$

Steps for Solving Linear Equation

Use the distributive property to multiply 5 by 10x+8.

$$A=50x+40$$

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

$$50x+40=A$$

Subtract 40 from both sides.

$$50x=A-40$$

Divide both sides by 50.

$$\frac{50x}{50}=\frac{A-40}{50}$$

Dividing by 50 undoes the multiplication by 50.

$$x=\frac{A-40}{50}$$

Divide A-40 by 50.

$$x=\frac{A}{50}-\frac{4}{5}$$

Solve for A

$$A=50x+40$$

Solution Steps

Use the distributive property to multiply 5 by 10x+8.

$$A=50x+40$$
