Had to do it to em
ohaa [14]

Answer:

A is the correct answer

Step-by-step explanation:

When x =4 and y =-5, and you want to evaluate equation -3x+2y, you just have to apply it into the equation.

We got the equation as:

= -3x + 2y

= -3*4 + 2*(-5)

= -12 + (-10)

= -12 - 10

= -22

Hope this help you :3
