4(4x - 3)=-76 explain you solution process

4(4x - 3)=-76

mutiply the bracket by 4

(4)(4x)= 16x

(4)(-3)= -12

16x-12= -76

move -12 to the other side

sign changes from -12 to +12

16x-12+12= -76+12

16x=-76+12

16x= -64

divide both sides by 16 to get x by itself

16x/16= -64/16

Cross out 16 and 16, divide by 16 and then becomes 1*1*x= x

x=-64/16

x=-4

1/4 because there is 4 grades.

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. : )
