$y = \frac{9}{5} X + 32$

Step 1

Rewrite the equation as $\frac{9}{5} X + 32 = y$ .

$\frac{9}{5} X + 32 = y$

Step 2

Combine $\frac{9}{5}$ and $X$ .

$\frac{9 X}{5} + 32 = y$

Step 3

Subtract $32$ from both sides of the equation.

$\frac{9 X}{5} = y - 32$

Step 4

Multiply both sides of the equation by $\frac{5}{9}$ .

$\frac{5}{9} \cdot \frac{9 X}{5} = \frac{5}{9} (y - 32)$

Step 5

Simplify both sides of the equation.
