Answer:

x = 3 / y = 6

Step-by-step explanation:

5x - 2y = 3

-5x + 4y = 9

-----------------   (combine the equations)

2y = 12

isolate the variable

y = 6

next, use one of the original equations and substitute in for y to solve for x

5x - 2(6) = 3

multiply

5x - 12 = 3

isolate the variable

5x = 15

divide each side by 5

x = 3
