Answer 1

Answer: A

The addition property of equality and then the division property of equality

Explanation:

just did the quiz

Answer 2

Find the solution below

Explanation:

The expression is incomplete. Let say the expression is 4 (-2u + 7) = 44

Given the expression

4 (-2u + 7) = 44

Step 1: Open the bracket by distributing 4 over -2u and 7

4 (-2u + 7)= 44

4(-2u) + 4(7) = 44 (distributive property)

-8u + 28 = 44

Step 2: Subtract 28 from both sides

-8u + 28 - 28 = 44 - 28 (subtraction property of equality)

-8u = 16

Step 3: Divide both sides by -8

-8u/-8 = 16/-8 (division property)

u = -2
