5x  =  20, solve for the value of x

x = 20 or what is 20?

200

h - 20 = 23 - 2

x = 41

300

y/3 = 8

y = 24

400

7P - 8 =  76

p =12

500

9n + 5 = 7(11)

n = 8

linear equation on both sides

100

x + 6 = 2x

x = 6

200

2x +  7 = 4x 

x= 3.5 

300

5r + 31 = 12r + 3

r =4

400

-7x + 9 =  4x - 123

x = 12

500

6w - 9 = 6w + 9

No solution

combining like terms equations

100

3n + 3n - 2 = −3n +  7

n = 4

200

4x + 7 + 3x - 2 = 68 

x = 9

300

2a  - 5  - 2 =  3a + 8 + 2a

a = -5

400

6x + 11 -  -3x = 12x + 25 - 4x

x = 14

500

7x + x  = 7x

x = any number

equations with distributive property
