The solution is x=3 , y=-4 or (3,-4)
Step-by-step explanation:
Given equations (1 and 2) are:

To solve a system of equation with elimination method, the co-efficients of one of the variables has to be equated and then the equations are added or subtracted to get an equation in one variable.
Multiplying equation 1 by 2:

Multiplying equation 2 by 3

Adding equation 3 and 4

Putting y = -4 in equation 1

Hence,
The solution is x=3 , y=-4 or (3,-4)
