1. Which set of steps shows the solution to the equation 4y = −12? (5 points)


y = −12 − 4; y = 8

y = −12 ÷ (−4); y = 3

y = −12 − (−4); y = −8

y = −12 ÷ 4; y = −3


2. Which statement is true for the equation 3x − 3x − 2 = −2? (5 points)


It has no solution.

It has one solution.

It has two solutions.

It has infinitely many solutions.

Answer 1

y = −12 ÷ 4; y = −3

Explanation:

Answer 2

1. y = −12 ÷ 4; y = −3

2. It has infinitely many solutions.

Explanation:

1. Divide both sides by 4, you will get y=-3

2. It has infinitely many solutions since x can be anything because the x's cancel, there are infinitely many x-values that make this equation work.

It means infinite solution.
