Answer:
and 
Step-by-step explanation:
Given:
.......................... equation i
........................ equation ii
since y is equals to the two functions , we can equate the two values of y . That is , equate equation i and ii , we have

Add
to both sides , we have


subtract 3 from both sides , we have

divide both sides by 4 , then

substitute
into equation i to get the value of y , that is



Therefore :
and

<span>Simplifying
z + 18 = y
Reorder the terms:
18 + z = y
Solving
18 + z = y
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-18' to each side of the equation.
18 + -18 + z = -18 + y
Combine like terms: 18 + -18 = 0
0 + z = -18 + y
z = -18 + y
Simplifying
z = -18 + y</span>
