The solution is (-4,4)
Step-by-step explanation:
Given equations are:

In linear combination method, we have to make coefficients of any one variable opposites by multiplying with an integer
So multiplying 2nd equation by -2

Adding Equation 1 and Equation 3:

Dividing both sides by 3

Putting y=-4 in equation 1

Dividing both sides by 4

Hence,
The solution is (-4,4)
