<h3>Answer: See the diagram below</h3>

Explanation:

In the LS column, you'll have these steps

3x - 1

3*4 - 1

12 - 1

11

Effectively, we replaced x with 4 and then simplified using PEMDAS.

And in the RS column, you'll have these steps

x + 7

4 + 7

11

We get the same thing at the bottom of each column. This shows that we end up with 11 = 11 after simplifying both sides. Therefore, we've confirmed that x = 4 is the solution to 3x - 1 = x + 7

What is the solution to the equation? 1 minus z/5=9 Answers: A. z = 50   B. z = 44   C. z = –2   D. z = – 40
gtnhenbr [62]
1 - \frac{z}{5} = 9

add \frac{z}{5} to both sides.

1 = 9 + \frac{z}{5}

subtract 9 to both sides.

-8 = \frac{z}{5} 

multiply 5 to both sides.

-40 = z

Your answer is D) z = -40
