15

Step-by-step explanation:

2x+3(x−10)=45

2x+(3)(x)+(3)(−10)=45

2x+3x+−30=45

(2x+3x)+(−30)=45

5x+−30=45

5x−30=45

5x−30+30=45+30

5x=75

x=15

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. : )
