If 4x =−16, 5y=20, and −11z=−11, then the value of -2y+3x-5z is:a.-25b.25c.-32d.32

To solve this problem, we first need to find the values of x, y, and z.

From 4x = -16, we can find x by dividing both sides by 4. This gives us x = -16 / 4 = -4.

From 5y = 20, we can find y by dividing both sides by 5. This gives us y = 20 / 5 = 4.

From -11z = -11, we can find z by dividing both sides by -11. This gives us z = -11 / -11 = 1.

Now we can substitute these values into the expression -2y + 3x - 5z.

This gives us -2(4) + 3(-4) - 5(1) = -8 - 12 - 5 = -25.

So, the value of -2y + 3x - 5z is -25. Therefore, the answer is a. -25.
