What is the first step in solving multi step equations?

Isolate the variable

100

2(x + 3) = 22

x = 8

100

| x + 5 | = 9

x = 4 , x = -14 

100

5 (x + 6) = -9x + 2

x = -2

100

Write a numerical expression for the sum of 3 and twice d

3 + 2d

200

How many solutions will you have when solving an absolute value equations?

2

200

-4x + 8 = 16

x = -2

200

| x - 6 | = 10

x= 16 , or x = -4 

200

2x + 3 = 19 + x

x = 16

200

Solve:

2x - 3 = 3x - 12

x = 9

300

What should I do to make sure my solutions are correct?

Check my work by substituting the values back into the original question. 

300

5 (x + 6) = 25

x = -1

300

3 | x - 4 | = 21

x =  11, or x = -3 

300

8(1 + 5x) + 5 = 13 + 5x

x = 0

300

| w - 1 | = 4

w = -3 or w = 5

400

The absolute value is always _____

positive

400

x/4  + 12 = 48

x = 144

400

6 | x - 3 | = 42

x = 10  or x = -4 

400

2(4x - 5) = 7x + 1

x = 11

400

Solve:

3x = 7x - 4

x = 1

500

What is the first step in solving an absolute value equation?

Write the two cases

500

2(3x - 4) + 8 = 6

x = 1

500

4 | x + 2 | + 3 = 7

x=-1 or x=-3

500

-3x + 4 = 2x +19

x = -3

500

Solve the proportion.   (x+4)/12 = 4x/24

x = 4
