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`

`y= -2+9`

`y= 7`

By using the substitution method, in coordinate form the solution to the system of equations is (2,7).
