So the best method is elimination method. This is what you do.
-5x + 2y = 9 3x + 5y = 7 You need to cancel out one variable so lets cancel out the x-value. Multiply the top equation by 3 and multiply the bottome by 5. Your new set of equations is. -15x + 6y = 27 15x +25y = 35 Add both equations. 31y = 62 Divide. y = 2 Plug in 2 into one of the equations. 3x + 5(2) = 7 3x + 10 = 7 Subtract 10 3x = -3 Divide x = 1 So your solution is (-1,2) I hope this helps love! :)
