Solve 8a=4-b,b

$$8 a = 4 - b , b$$

Solve for a

$$a=-\frac{b}{8}+\frac{1}{2}$$

Steps for Solving Linear Equation

The equation is in standard form.

$$8a=4-b$$

Divide both sides by 8.

$$\frac{8a}{8}=\frac{4-b}{8}$$

Dividing by 8 undoes the multiplication by 8.

$$a=\frac{4-b}{8}$$

Divide 4-b by 8.

$$a=-\frac{b}{8}+\frac{1}{2}$$

Solve for b

$$b=4-8a$$

Steps for Solving Linear Equation

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

$$4-b=8a$$

Subtract 4 from both sides.

$$-b=8a-4$$

Divide both sides by -1.

$$\frac{-b}{-1}=\frac{8a-4}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$b=\frac{8a-4}{-1}$$

Divide 8a-4 by -1.

$$b=4-8a$$
