Tracy solved the system of equations by making a substitution for x in the second equation.

What equation did she get as a result of that substitution?

x = - 2y - 2

2x + 3y = - 6

-2y - 2 = - 6

-2y + 1 = - 6

-4y - 2 + 3y = - 6

-4y - 4 + 3y = - 6

Hannah Steele · Answer 1

Tracy put (-2y-2) where x is in the second equation. This resulted in

2 (-2y-2) + 3y = - 6

After eliminating parentheses, Tracy had

-4y - 4 + 3y = - 6

The 4th selection is appropriate:

-4y - 4 + 3y = - 6
