Answer 2

3(x+1)−2(x−1)=−x+5

2

 

Regroup terms.

3(x+1)-2(x-1)=5-x3(x+1)−2(x−1)=5−x

3

 

Expand.

3x+3-2x+2=5-x3x+3−2x+2=5−x

4

 

Simplify  3x+3-2x+23x+3−2x+2  to  x+5x+5.

x+5=5-xx+5=5−x

5

 

Cancel 55 on both sides.

x=-xx=−x

6

 

Subtract -x−x from both sides.

x+x=0x+x=0

7

 

Simplify  x+xx+x  to  2x2x.

2x=02x=0

8

 

Divide both sides by 22.

x=0x=0
