Eliminate the equal sides of each equation and combine.
Add `x` to both sides of the first equation in order to get the variable on one side. Continue to pull down the second equation.
Now add `5` to both sides of the first equation.
Divide each term of the first equation by `7` .
`(7x)/7 = 14/7`
Now we can replace `x=2` into `y=-x+9`
By using the substitution method, in coordinate form the solution to the system of equations is (2,7).
