Solve 3-4=x-y

$$3 - 4 = x - y$$

Solve for x

$$x=y-1$$

Solution Steps

Subtract 4 from 3 to get -1.

$$-1=x-y$$

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

$$x-y=-1$$

Add y to both sides.

$$x=-1+y$$

Solve for y

$$y=x+1$$

Steps for Solving Linear Equation

Subtract 4 from 3 to get -1.

$$-1=x-y$$

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

$$x-y=-1$$

Subtract x from both sides.

$$-y=-1-x$$

The equation is in standard form.

$$-y=-x-1$$

Divide both sides by -1.

$$\frac{-y}{-1}=\frac{-x-1}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$y=\frac{-x-1}{-1}$$

Divide -1-x by -1.

$$y=x+1$$
