If we add the 2 equations the terms in x dssappear and we get
2y = 1
so y = 1/2
Substitute in first equtaion:-
1/2 = - 1/2 x + 4
-1/2 x = 1/2 - 4 = - 7/2
x = -7/2 * -2 = 14/2 = 7
answer is (7, 1/2)
Answer:
Question 1: -3 and 6 in that order
Question 3: 3 and y=1/2x+3 in that order
Question 2: 2 and y=2x+4 in that order
