Question

What is the value of y in the equation 4 + y = −3?

7
1
−1
−7

Answer 1

-7

Explanation:

4 + y = -3

-4 + 4 + y = -3 - 4

y = -7

Answer 2

-7 is your answer

Explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other.

4 + y = -3

Subtract 4 from both sides

4 (-4) + y = -3 (-4)

y = -3 - 4

y = -7

-7, or (D) is your answer
