MULTIPLE CHOICE QUESTION

Which answer has a correct next step for this system? (Read all three answers carefully before selecting one!)


y = 6x

2x + 5y = 32

The variable is already isolated, so we've already solved the system.

The variable is already isolated for y, so we substitute it in the second equation like this:

2(6x) + 5y = 32

The variable is already isolated for y, so we substitute it in the second equation like this:

2x + 5(6x) = 32

Use the system of equations below to answer the question.


After substituting the first equation into the second one and working it out, I got x = 1. What should I do next?


y = 6x

2x + 5y = 32

Fill in 1 for x in y = 6x

Fill in 1 for y in y = 6x

Fill in 1 for y in 2x + 5y = 32

Which answer has a correct next step for this system? (Read all three answers carefully before selecting one!)


3x + 4y = 3

y = 3x + 5

The variable is already isolated, so we've already solved the system.

The variable is already isolated for y, so we substitute 3x + 5 in the first equation like this:

3x + 4(3x + 5) = 3

The variable is already isolated for y, so we substitute 3x + 5 in the second equation like this:

3(3x + 5) + 4y = 3
