Solve (2-1)x-(1-1)y-5+1=0

$$( 2 - 1 ) x - ( 1 - 1 ) y - 5 + 1 = 0$$

Solve for x

$$x=4$$

Steps for Solving Linear Equation

Subtract 1 from 2 to get 1.

$$1x-\left(1-1\right)y-5+1=0$$

Subtract 1 from 1 to get 0.

$$1x-0y-5+1=0$$

Anything times zero gives zero.

$$1x-0-5+1=0$$

Add -5 and 1 to get -4.

$$1x-0-4=0$$

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

$$1x-0=4$$

Add 0 to both sides.

$$1x=4+0$$

Add 4 and 0 to get 4.

$$1x=4$$

Reorder the terms.

$$x=4$$

Solve for y (complex solution)

$$y\in \mathrm{C}$$

$$x=4$$

Solve for y

$$y\in \mathrm{R}$$

$$x=4$$
