Select the answer for the question shown below.

It has one solution

Step-by-step explanation:

3/4 z = 1/4 z - 3 + 5

Subtract 1/4 z on both sides:

2/4 z = -3 + 5

2/4 z = 2

1/4 z = 1

Substitute:

3 = 1 - 3 + 5

3 = -2 + 5

3 = 3

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
