Answer:
x=-2
Step-by-step explanation:
Part a), solve this system of equations:
x + y = 5
x - y = 2.25
2x = 7.25
x = 3.625
y = 1.375
part b), solve this system of equations:
x + y = 5
x = 3y
y = 1.25
x = 3.75
The Solution.
The given equation is

Substituting 11 for x, we can get the value of y.

Hence, the value of y is 18.
