Solve (6-y)*90=480

$$( 6 - y ) \cdot 90 = 480$$

Solve for y

$$y=\frac{2}{3}\approx 0.666666667$$

Steps for Solving Linear Equation

Divide both sides by 90.

$$6-y=\frac{480}{90}$$

Reduce the fraction \frac{480}{90} to lowest terms by extracting and canceling out 30.

$$6-y=\frac{16}{3}$$

Subtract 6 from both sides.

$$-y=\frac{16}{3}-6$$

Convert 6 to fraction \frac{18}{3}.

$$-y=\frac{16}{3}-\frac{18}{3}$$

Since \frac{16}{3} and \frac{18}{3} have the same denominator, subtract them by subtracting their numerators.

$$-y=\frac{16-18}{3}$$

Subtract 18 from 16 to get -2.

$$-y=-\frac{2}{3}$$

Multiply both sides by -1.

$$y=\frac{2}{3}$$
