Solve 12x-4y-15=0

$$12 x - 4 y - 15 = 0$$

Solve for x

$$x=\frac{y}{3}+\frac{5}{4}$$

Steps for Solving Linear Equation

Add 4y to both sides. Anything plus zero gives itself.

$$12x-15=4y$$

Add 15 to both sides.

$$12x=4y+15$$

Divide both sides by 12.

$$\frac{12x}{12}=\frac{4y+15}{12}$$

Dividing by 12 undoes the multiplication by 12.

$$x=\frac{4y+15}{12}$$

Divide 4y+15 by 12.

$$x=\frac{y}{3}+\frac{5}{4}$$

Solve for y

$$y=3x-\frac{15}{4}$$

Steps for Solving Linear Equation

Subtract 12x from both sides. Anything subtracted from zero gives its negation.

$$-4y-15=-12x$$

Add 15 to both sides.

$$-4y=-12x+15$$

The equation is in standard form.

$$-4y=15-12x$$

Divide both sides by -4.

$$\frac{-4y}{-4}=\frac{15-12x}{-4}$$

Dividing by -4 undoes the multiplication by -4.

$$y=\frac{15-12x}{-4}$$

Divide -12x+15 by -4.

$$y=3x-\frac{15}{4}$$
