Solution Steps

Consider the third equation. Insert the known values of variables into the equation.

$$o=1\times 30+8-12\times \frac{1}{4}$$

Multiply 1 and 30 to get 30.

$$o=30+8-12\times \frac{1}{4}$$

Add 30 and 8 to get 38.

$$o=38-12\times \frac{1}{4}$$

Multiply -12 and \frac{1}{4} to get -3.

$$o=38-3$$

Subtract 3 from 38 to get 35.

$$o=35$$
