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

Explanation:

In the LS column, you'll have these steps

3x - 1

3*4 - 1

12 - 1

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

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

Answer:

$y = x-7$

Step-by-step explanation:

Step 1: Write the equation in point-slope form

Point Slope Form: $y-y_{1}=m\left(x-x_{1}\right)$

Plug in the numbers and solve

$y - (-2) = 1(x - 5)$

$y + 2 = x - 5$

$y + 2 - 2 = x - 5 - 2$

$y = x-7$

Answer: $y = x-7$

PLEASE HELP 2O POINTS

C. The first is a solution, but the second is not.

5x - y/3 = 13 ; (2,-9)
substitute the letters:
5(2) - (-9/3) = 13
10 - (-3) = 13 : note that deducting a number with a negative sign turns both sign as positive.
10 + 3 = 13 ;
13 = 13

5x - y/3 = 13 ; (3,-6)
5(3) - (-6/3) = 13
15 - (-2) = 13
15 + 2 = 13
17 = 13 not equal. not a solution

hope i could help
