Question

Which equation below would be best solved by using the addition property of equality?

- 23=45

237=45

F+23=45

F-23=45

Answer 1

the answer is D

Explanation:

Answer 2

Answer: F-23=45

Explanation:

The addition property of equality means that if:

A = B

then we can add the same thing in both sides of the equation, and the equality will remain balid, so:

A + C = B + C.

Then, the correct answer is the last option:

if

F - 23 = 45

Then we can add the same number to both sides, we can add 23 to both sides and in this way isolate F:

F - 23 = 45

(F - 23) + 23 = 45 +23 = 68

F + (23 - 23) = 68

F = 68
