Answer:
The value of y is - 11
Step-by-step explanation:
The first statement is written as
6y + x = -62.......... equation 1
The second statement is written as
x - y = 15 ........ equation 2
To find y make x the subject in the second equation and substitute it into the first equation
That's
x = 15 + y
6y + x = - 62
6y + 15 + y = -62
7y = -62 - 15
7y = - 77
Divide both sides by 7
y = - 11
Hope this helps you.
