Question

Question 7 using substitution if you don’t mind. Help please.

Answer 1

y= -2 and x= 1 according to the solution in the picture

Answer 2

x = 1

y = -2

Explanation:

3x - 2y = 7

4x + y = 2 then y = 2 - 4x

substitute for y:

3x - 2(2 - 4x) = 7

reduce:

3x - 4 + 8x = 7

11x = 11

x = 1

y = -2
