B.
Apply the addition property of equality first, and then apply the multiplication property of equality to isolate the variable.
C.
Apply only the multiplication property of equality to isolate the variable.
D.
Apply only the addition property of equality to isolate the variable.

Answer 1

It depends on the equation.

Answer 2

there is no equation

Answer 3

Look at the equations:

y=5n - 9

y=5(n-9)

There is no "best" way. You just apply inverse operations in the opposite order.

Answer 4

so D?

Answer 5

What is a "two-step equation"?

Answer 6

wait is it B ?

Answer 7

two-step equation means what?

Answer 8

It depends on what order the steps were taken.

Look at the equations above and try and solve for n.

Answer 9

an equation that takes two steps to be solved ?

Answer 10

The steps are in the opposite order for the two equations that I wrote.

Answer 11

subtraction then multiplication

Answer 12

I would choose B

B.
Apply the addition property of equality first, and then apply the multiplication property of equality to isolate the variable.

Answer 13

But I don't like the question.

Answer 14
