Solve by Graphing x+y=8 , x-y=6

$x + y = 8$ , $x - y = 6$

Step 1

Subtract $x$ from both sides of the equation.

$y = 8 - x$

$x - y = 6$

Step 2

Subtract $x$ from both sides of the equation.

$- y = 6 - x$

$y = 8 - x$

Step 3

Divide each term in $- y = 6 - x$ by $- 1$ and simplify.

Divide each term in $- y = 6 - x$ by $- 1$ .

$\frac{- y}{- 1} = \frac{6}{- 1} + \frac{- x}{- 1}$

$y = 8 - x$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{y}{1} = \frac{6}{- 1} + \frac{- x}{- 1}$

$y = 8 - x$

Divide $y$ by $1$ .

$y = \frac{6}{- 1} + \frac{- x}{- 1}$

$y = 8 - x$

$y = \frac{6}{- 1} + \frac{- x}{- 1}$

$y = 8 - x$

Simplify the right side.

Simplify each term.

Divide $6$ by $- 1$ .

$y = - 6 + \frac{- x}{- 1}$

$y = 8 - x$

Dividing two negative values results in a positive value.

$y = - 6 + \frac{x}{1}$

$y = 8 - x$

Divide $x$ by $1$ .

$y = - 6 + x$

$y = 8 - x$

$y = - 6 + x$

$y = 8 - x$

$y = - 6 + x$

$y = 8 - x$

$y = - 6 + x$

$y = 8 - x$

Step 4

Create a graph to locate the intersection of the equations. The intersection of the system of equations is the solution.
