Question

For the equation below, if x = -5, then y must equal...  x - 5y = -15 Select one: a. 4 b. -2 c. 2 d. -4

Answer 1

When x equals -5 for the equation x - 5y = -15, y must equal 2 after substituting -5 into the equation and solving for y.

Step-by-step explanation:

To determine the value of y when x = -5 for the equation x - 5y = -15, you would substitute -5 for x and then solve for y.

Substituting x into the equation gives us:

-5 - 5y = -15

Now, solve for y step-by-step:

1. Add 5 to both sides of the equation: -5y = -15 + 5
2. Simplify the right-hand side: -5y = -10
3. Divide both sides by -5 to derive y: y = 2

Therefore, when x = -5, y must equal 2.
