Solve 2x+4y=142

$$2 x + 4 y = 142$$

Solve for x

$$x=71-2y$$

Steps for Solving Linear Equation

Subtract 4y from both sides.

$$2x=142-4y$$

Divide both sides by 2.

$$\frac{2x}{2}=\frac{142-4y}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$x=\frac{142-4y}{2}$$

Divide 142-4y by 2.

$$x=71-2y$$

Solve for y

$$y=\frac{71-x}{2}$$

Steps for Solving Linear Equation

Subtract 2x from both sides.

$$4y=142-2x$$

Divide both sides by 4.

$$\frac{4y}{4}=\frac{142-2x}{4}$$

Dividing by 4 undoes the multiplication by 4.

$$y=\frac{142-2x}{4}$$

Divide 142-2x by 4.

$$y=\frac{71-x}{2}$$
