if x =3 and y = -4, find the value of 8x -10y

I will be happy to critique your work/ or thinking on this.

To find the value of 8x - 10y, we need to substitute the given values of x and y and perform the required calculations.

Given:
x = 3
y = -4

Substituting these values into the expression, we have:
8x - 10y = 8(3) - 10(-4)

Now, let's simplify the expression:
8(3) = 24
-10(-4) = 40

Substituting these values back into the expression, we have:
8x - 10y = 24 - 40

Finally, performing the subtraction:
8x - 10y = -16

Therefore, the value of 8x - 10y is -16.
