Hello there !
2 x − 3 y = 14 2 x − y = − 10 2 x − 3 y = 14 2 x = y − 10 y − 10 − 3 y = 14 − 10 − 14 = − y + 3 y − 24 = 2 y − 12 = y 2 x − y = − 10 2 x − ( − 12 ) = − 10 2 x = − 10 − 12 2 x = − 22 = − 11
The solution to the system of equations is x = − 11 and y = − 12 . This was achieved by using the elimination method and substituting values. The final set of values provides an accurate resolution to the system.
