To find the variables of the equations, use systems of equations.
First get rid of one variable. Let's get rid of the y by multiplyin both equations nad then adding them. ( 6 x − 2 y = 33 ) 3 ( 4 x + 3 y = 9 ) 2
18 x − 6 y = 99 8 x + 6 y = 18 26 x = 117
Solve for x: 26 26 x ​ = 26 117 ​ x = 4.5
Now you have x! Plug x into one quation and solve for y: 6 ( 4.5 ) − 2 y = 33 27 − 2 y = 33 − 2 − 2 y ​ = − 2 6 ​ y = − 3
x = 4.5 , y = − 3

The solution to the system of equations is x = 2 9 ​ and y = − 3 . This was done by solving one equation for x and substituting it into the other equation. The method used was substitution to find the values of x and y .
