100

Which of the following are like terms?

2x, 3, 4x, x

2x, 4x, and x

200

Are the following like terms?

4x² and 4x

no

300

Combine the following like terms.

4x + 3y + 7y - 9x

-5x + 10y

400

Simplify the following:

4(x - 3) - 10

4x - 22

500

Simplify the following.

8(x + 1) + 6(1 - 2x)

-4x + 14

What step do I do first?

100

8x - 1 = -17

Addition of 1 to both sides

200

8 + 0.5d = 16

Subtract by 8 to both sides

300

4(3x - 1) = 8

Distribute 

400

8x + 4 - 2x = 16

Combine Like terms

500

(2x - 4)/-8 = 10

Multiply by -8

What step do I do second?

100

18 = 4x - 18

Divide by 4

200

(x - 1)/3 = -2

Add 1

300

4x - 6x + 2 = 8

Step 1 is combine like terms, Step 2 is to subtract 2

400

8(2x - 3) = 16

Step 1-Distributive Property

Step 2 - Add 24

500

6x+2(x - 4) = 80

Step 1 - Distributive Property

Step 2 - Combine Like Terms
