Question

Select all of the equations below that are equivalent to:

8 = k − 3

Use properties of equality.

Answer 1

the two equation on the top line

Explanation:

8 = k - 3

Subtract 15 from each side: 8 - 15 = k - 18 Equivalent

Subtract 12 from each side: 8 - 12 = k - 15 Equivalent

Subtract 5 from each side: 8 - 5 = k - 8 Equivalent, so 8 - 5 = k - 7 is not equivalent

Subtract 10 from each side: 8 - 10 = k - 13 Equivalent, so 8 - 10 = k - 12 is not equivalent

Answer: the two equation on the top line
