Question

Solve the equation for x
3x + 20 = x - 8

Answer 1

Answer:

x=−14

Step-by-step explanation:

Step 1: Subtract x from both sides.

3x+20−x=x−8−x

2x+20=−8

Step 2: Subtract 20 from both sides.

2x+20−20=−8−20

2x=−28

Step 3: Divide both sides by 2.

2x

2

=

−28

x=−14

Answer 2

Answer:

x = 9.33333333333

Step-by-step explanation:

How to solve...

3x + 20 = x - 8

     +   8 = x + 8

----------------------  ( add 8 on both sides )

  3x + 28 = x

 3x  + 28 = 3x

---------------------- ( divide 3x on both sides )

     28 = 3x

      3  =  x

---------------------- ( divide 28 by 3 )

x = 9.33333333333
