Answer 5

see the 2nd equation :
x=7y+3

replace the 7y to left side, it becomes
x - 7y = 3

now add both equations above :
-2x + 7y = 22
x - 7y = 3
------------- +
-x = 25
x = -25

to get y, subtitute x = -25 into the 1st equation.

-2x + 7y = 22
-2(-25) + 7y = 22
50 + 7y = 22
7y = 22 - 50
7y = -28
y = -28/7
y = -4
