Question

Solve for a.

a+(−7)=−17

What is the answer?

a=−24
a=−10
a = 10
a = 24

Answer 1

Hey there!

In order to simplify this equation, we can use our properties of negatives. We know that:

(x)+(-y) = x - y

Therefore, we can simplify this equation to:

a - 7 = 17

Using the additive algebraic property of equality, we can add 7 to both sides to get:

a = 24

Therefore, your answer is the last one, a = 24.

Hope this helps!
