Question

Given the equation 11.5 - 3y = -48.5, what are the equivalent equations? Choose all that apply.

Answer 1

Answer:

B. y=20

Step-by-step explanation:

Replace -3y with -3(20) to get -60

Now solve for -48.5

11.5-60=-48.5

When you add a positive number to a negative number, you subtract and add the negative to the answer when you are finished.

60-11.5=48.5 meaning 11.5-60=-48.5

If -48.5=-48.5, it means that B is the correct answer.

Answer 2

Answer:

-3y = -60  and y=20

Step-by-step explanation:

11.5 - 3y= -48.5  subtract 11.5 from bothh sides

-3y = -60  divide both sides by -3

y=20
