Solve 4a+2b=0

$$4 a + 2 b = 0$$

Solve for a

$$a=-\frac{b}{2}$$

Steps for Solving Linear Equation

Subtract 2b from both sides. Anything subtracted from zero gives its negation.

$$4a=-2b$$

Divide both sides by 4.

$$\frac{4a}{4}=-\frac{2b}{4}$$

Dividing by 4 undoes the multiplication by 4.

$$a=-\frac{2b}{4}$$

Divide -2b by 4.

$$a=-\frac{b}{2}$$

Solve for b

$$b=-2a$$

Steps for Solving Linear Equation

Subtract 4a from both sides. Anything subtracted from zero gives its negation.

$$2b=-4a$$

Divide both sides by 2.

$$\frac{2b}{2}=-\frac{4a}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$b=-\frac{4a}{2}$$

Divide -4a by 2.

$$b=-2a$$
