Answer:
value of y: 14.5
value of x: -5
Explanation:
The reason I put two values is that I am going to assume that you meant the value of x rather than the value of y. When we plugin y = 14.5 into the equation we get
14.5 = -2x + 4.5
When subtracting 4.5 we get:
10 = -2x
When dividing by -2 we get:
-5 = x
Therefore the value of x is -5.
The value of y is 14.5 because you are just using the same variable (no math required).
