Solve 4(x-3)=y

$$4 ( x - 3 ) = y$$

Solve for x

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

Steps for Solving Linear Equation

Use the distributive property to multiply 4 by x-3.

$$4x-12=y$$

Add 12 to both sides.

$$4x=y+12$$

Divide both sides by 4.

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

Dividing by 4 undoes the multiplication by 4.

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

Divide y+12 by 4.

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

Solve for y

$$y=4\left(x-3\right)$$

Solution Steps

Use the distributive property to multiply 4 by x-3.

$$4x-12=y$$

Swap sides so that all variable terms are on the left hand side.

$$y=4x-12$$
