Solve 8x-10y+66=0

$$8 x - 10 y + 66 = 0$$

Solve for x

$$x=\frac{5y-33}{4}$$

Steps for Solving Linear Equation

Add 10y to both sides. Anything plus zero gives itself.

$$8x+66=10y$$

Subtract 66 from both sides.

$$8x=10y-66$$

Divide both sides by 8.

$$\frac{8x}{8}=\frac{10y-66}{8}$$

Dividing by 8 undoes the multiplication by 8.

$$x=\frac{10y-66}{8}$$

Divide 10y-66 by 8.

$$x=\frac{5y-33}{4}$$

Solve for y

$$y=\frac{4x+33}{5}$$

Steps for Solving Linear Equation

Subtract 8x from both sides. Anything subtracted from zero gives its negation.

$$-10y+66=-8x$$

Subtract 66 from both sides.

$$-10y=-8x-66$$

Divide both sides by -10.

$$\frac{-10y}{-10}=\frac{-8x-66}{-10}$$

Dividing by -10 undoes the multiplication by -10.

$$y=\frac{-8x-66}{-10}$$

Divide -8x-66 by -10.

$$y=\frac{4x+33}{5}$$
