Solve x=-130+x+y-(170-y)

$$x=-130+x+y-(170-y)$$

Solve for y

$$y=150$$

Steps for Solving Linear Equation

To find the opposite of 170-y, find the opposite of each term.

$$x=-130+x+y-170+y$$

Subtract 170 from -130 to get -300.

$$x=-300+x+y+y$$

Combine y and y to get 2y.

$$x=-300+x+2y$$

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

$$-300+x+2y=x$$

Add 300 to both sides.

$$x+2y=x+300$$

Subtract x from both sides.

$$2y=x+300-x$$

Combine x and -x to get 0.

$$2y=300$$

Divide both sides by 2.

$$y=\frac{300}{2}$$

Divide 300 by 2 to get 150.

$$y=150$$

Solve for x (complex solution)

$$x\in \mathrm{C}$$

$$y=150$$

Solve for x

$$x\in \mathrm{R}$$

$$y=150$$
