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