<u>Step-by-step explanation:</u>
We are given two equations:
; and
Since y is the subject for both the equations so we can put the values of y equal to each other to get:
Factorizing the expression to get:
Putting x = 2 and x = -6 in any of the equations to get the values of y:
and
Therefore, solution to these equation is (2, 7) or (-6, 1).
