200

Solve for x. 

4x = 20

x = 5

200

-3x - 12 = 24

x = -12

200

Solve 

-4x - 6x + 5 = 25

x = -2

200

Solve 

5x + 4 = 3x - 6

x = -5

200

Distribute this:

-3(5x-7)

-15x + 21

300

-3x = 36

x = -12

300

Solve. 30 - x = 60

x = -30

300

Solve 

3x - 9+ 5x - 7 = 16

x = 4

300

Solve 

4(x-8) = 3x +8

x = 40

Combine the following like terms:


-4a + 6 - 7b - 10a -20

-14a - 7b - 14

400

x/4 = -15

x = -60

400

x/3 + 17 = 34

x = 51

400

Solve 

3(-5x - 4) - 20 = 28

x = -4

400

Solve for x

9x - 4x + 2 - 7 = -20 - 10x

x = -1

400

Combine the following like terms:


-4x + 6y - 23x + 65 - 4(2x-5) - y


-35x + 5y +85

500
x/-8 = -20

x = 160

(x-4)/3 = 12

x = 40

500

3(x-4) - (x+7) = 1

x = 10

500

3(x-13) -4(x+5) = 7(7x-4) + 6(2x-5) - 1


x = 0
