Solving equations

Variable one side

100

2x-7=5

x=6

200

7x-8= 25

x=33/7

variable both sides

100

2x-6=-5x+8x=

x=2

200

2x+9=4x- 5x-8

x=-17/3

distribution required

100

10=3- 2(2x+5)

x=-17/4

200

3(2x-5)=17

x=16/3

distribution and variable both sides

100

-2x=3(x+2)

x=-6/5

200

2(5x-3)=3(2x+1)

x=9/4

absolute value equations

100

abs(x)=2x-5

x=5 ,x=5/3

200

abs(x-1)=7

x=8 and x=-6
