Solve -45x+36y=72

$$- 45 x + 36 y = 72$$

Solve for x

$$x=\frac{4\left(y-2\right)}{5}$$

Steps for Solving Linear Equation

Subtract 36y from both sides.

$$-45x=72-36y$$

Divide both sides by -45.

$$\frac{-45x}{-45}=\frac{72-36y}{-45}$$

Dividing by -45 undoes the multiplication by -45.

$$x=\frac{72-36y}{-45}$$

Divide 72-36y by -45.

$$x=\frac{4y-8}{5}$$

Solve for y

$$y=\frac{5x}{4}+2$$

Steps for Solving Linear Equation

Add 45x to both sides.

$$36y=72+45x$$

The equation is in standard form.

$$36y=45x+72$$

Divide both sides by 36.

$$\frac{36y}{36}=\frac{45x+72}{36}$$

Dividing by 36 undoes the multiplication by 36.

$$y=\frac{45x+72}{36}$$

Divide 72+45x by 36.

$$y=\frac{5x}{4}+2$$
