Answer: y is -1

x is 3

Step-by-step explanation:

make x the subject in equation 2

x = - 2y + 1

substitute x = - 2y + 1 into eegation 1

y = 2x - 7

y = 2 ( - 2y + 1 ) - 7

y = - 4y + 2 - 7

4y + y = - 5

5y = - 5

y = - 1

substitute y = - 1 into equation 2

x + 2y = 1

x + 2 ( -1 ) = 1

x = 2 + 1

x = 3

therefore x = 3

y = - 1
