Question

Which value of y makes the equation true? -2y − 9 = -11

a) -10
b) -1
c) 1
d) 10

Answer 1

To find the value of y that makes the equation -2y - 9 = -11 true, isolate the y term and solve for y. The value of y that makes the equation true is y = 1.

Step-by-step explanation:

To find the value of y that makes the equation -2y - 9 = -11 true, we need to solve for y.

To do this, we can start by isolating the y term by adding 9 to both sides of the equation:

-2y = -11 + 9

-2y = -2

Then, divide both sides of the equation by -2 to isolate y:

y = -2 / -2

This simplifies to y = 1.

Therefore, the value of y that makes the equation true is y = 1. This corresponds to option c) in your list of choices.
