Solve -2=-b/2a

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

Solve for a

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

$$b\neq 0$$

Steps for Solving Linear Equation

Variable a cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 2a.

$$-4a=-b$$

Divide both sides by -4.

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

Dividing by -4 undoes the multiplication by -4.

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

Divide -b by -4.

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

Variable a cannot be equal to 0.

$$a=\frac{b}{4}\text{, }a\neq 0$$

Solve for b

$$b=4a$$

$$a\neq 0$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 2a.

$$-4a=-b$$

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

$$-b=-4a$$

Divide both sides by -1.

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

Dividing by -1 undoes the multiplication by -1.

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

Divide -4a by -1.

$$b=4a$$
