Solve 1/4A+3A+8A=-450

$$\frac { 1 } { 4 } A + 3 A + 8 A = - 450$$

Solve for A

$$A=-40$$

Steps for Solving Linear Equation

Combine \frac{1}{4}A and 3A to get \frac{13}{4}A.

$$\frac{13}{4}A+8A=-450$$

Combine \frac{13}{4}A and 8A to get \frac{45}{4}A.

$$\frac{45}{4}A=-450$$

Multiply both sides by \frac{4}{45}, the reciprocal of \frac{45}{4}.

$$A=-450\times \frac{4}{45}$$

Express -450\times \frac{4}{45} as a single fraction.

$$A=\frac{-450\times 4}{45}$$

Multiply -450 and 4 to get -1800.

$$A=\frac{-1800}{45}$$

Divide -1800 by 45 to get -40.

$$A=-40$$
