2x +y= 2)
3х – 2y = -11
how do i solve for this? using elimination?

2 x = y + 3 , 4 x − 3 = 2 y

Rewrite the equation as y + 3 = 2 x . y + 3 = 2 x 4 x − 3 = 2 y Subtract 3 from both sides of the equation.

y = 2 x − 3 4 x − 3 = 2 y Rewrite the equation as 2 y = 4 x − 3 . y = 2 x − 3 2 y = 4 x − 3 Divide each term by 2 and simplify.

y = 2 x − 3 y = 2 x − 3 2 Create a graph to locate the intersection of the equations.

The intersection of the system of equations is the solution. No solution

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
