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).
