Question

PLZ HELP !!! ALGEBRA 1

Answer 1

Answer:

2 a. x= -2, x=10 2 b. x= -7, x=7

Step-by-step explanation:

move the -6 to the left to get

-7 x lx-4l = -42

divide both sides of the equation by -7

lx-4l = 6

separate into

x-4=6 and x-4= -6

solve by adding 4 to both sides

then on the other one add 4 to both sides

2b you do the same steps just different numbers

Answer 2

Answer:

1 a 12

1 b I have No Idea Sorry Man

2 a x = 10 or x = −2

2 b −10 x = 10 or −10x = −10

Step-by-step explanation:

2 a

6−7(|x−4|)=−36

−7(|x−4|)+6=−36

Step 1: Add -6 to both sides.

−7(|x−4|)+6+−6=−36+−6

−7(|x−4|)=−42

Step 2: Divide both sides by -7.

$\frac{-7(|x-4|)}{-7} =\frac{-42}{-7}$

|x−4|=6

Step 3: Solve Absolute Value.

|x−4|=6

We know either x−4=6 or x−4=−6

__________________________________________________________

2 B

−8(|−10x|)+1=−79

Step 1: Add -1 to both sides.

−8(|−10x|)+1+−1=−79+−1

−8(|−10x|)=−80

Step 2: Divide both sides by -8.

$\frac{-8(|-10x|)}{-8} =\frac{-80}{8}$

|−10x|=10

Step 3: Solve Absolute Value.

|−10x|=10

We know either−10x=10or−10x=−10
