and value of y is 
Step-by-step explanation:
We need to find Which expression could be substituted for y in the second equation to find the value of x
The given equations are:

For putting value of y in second equation, we will find from equation 1
From equation 1:

Putting value of y i.e y=10+2x in equation (2) to find value of x

So, now finding value of y by putting value of x= -29/4 in eq(1)

So, value of x is
and value of y is
