Answer:

x=27

Step-by-step explanation:

What you need to do is isolate the x or in other words have the x be alone on one side of the equal sign. To do this you would need to add 21 to both sides because you need to cancel out -21 with the opposite which would be positve 21. After that the x should be by itself and then finally add 21 to 6 to complete solving for x.

Write the equation of the line parallel to 3x-y=7 that passes through point (-5, -3)

IceJOKER [234]

<h2>Answer:</h2>

$\boxed{y=3x+12}$

<h2>Step-by-step explanation:</h2>

In this problem we know the equation of a line, which is:

$3x-y=7$

We also can write this equation as:

$y=3x-7$

This line has a slope $m=3$ which is also the slope of the line we are looking for because they're parallel. We also have a point $(-5,-3)$ . Therefore, we can write this equation as follows:
