Question 666462
Establish variables
x = Jorge
y = Ahmed
z = Kaitlin
...
Given
x = 2y + 5
z = x
x = 3y - 3
...
a.
Ahmed, y, can be solved setting the x expression equivalent to each other
2y + 5 = 3y - 3
...
b.
Setting the two x expressions equivalent to each other
2y + 5 = 3y - 3
2y - 3y = -3 - 5
-y = -8
Divide both sides by -1

Solving for x, Jorge
x = 2y + 5
x = 2(8) + 5 = 16 + 5
