Solve 15^2-7.2y=1

$${ 15 }^{ 2 } -7.2y=1$$

Solve for y

$$y = \frac{280}{9} = 31\frac{1}{9} \approx 31.111111111$$

Steps for Solving Linear Equation

Calculate 15 to the power of 2 and get 225.

$$225-7.2y=1$$

Subtract 225 from both sides.

$$-7.2y=1-225$$

Subtract 225 from 1 to get -224.

$$-7.2y=-224$$

Divide both sides by -7.2.

$$y=\frac{-224}{-7.2}$$

Expand \frac{-224}{-7.2} by multiplying both numerator and the denominator by 10.

$$y=\frac{-2240}{-72}$$

Reduce the fraction \frac{-2240}{-72} to lowest terms by extracting and canceling out -8.

$$y=\frac{280}{9}$$
