Pls explain and I will mark as brainliest too

sorry I also didn't understand this

First step count how many Red -1 there are: 21

so it's -21

so what we have now is

5x+4=-21

simplify this equation:

5x=-21-4

5X=-25

x=-5

so the answer is

answ5

step-by-step explanation:

u have to pay atttion to me

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
