Answer:

y = -3.75

3*3 - 8y = 39

9 - 8y = 39

-8y = 30

y = -30/8

y = -3.75

•••••••••••••••SOLUTION••••••••••••

3(3)-8y= 39

9 - 8y=. 39

8y= 30

Y= 30/8

Y=. -3.75 ANS
••••••••••••• CHECKING•••••••••••••

3(3) - 8(-3.75)= 39
9 + 30 = 39
39 = 39

As the LHS and RHS are equal so the value of y = (-3.75)
