Answer: 23/2 or 11.5

Explanation:

x - 10 = (x - 7) / 3

3 (x - 10) = x - 7

3x - 30 = x - 7

3x - x = 30 - 7

2x = 23

x = 23/2 answer...

change it into decimal form

x = 11.5 answer...

note: 23/2 or 11.5 both could be the answers

hope that helps...

Answer:

x = 23/2 or 11.5

Explanation:

Step 1: Multiply both sides by 3.


  • 3(x-10)= (x-7)/(3) *3

  • 3x - 30 = x - 7

Step 2: Subtract x from both sides.


  • 3x-30-x=x-7-x

  • 2x-30=-7

Step 3: Add 30 to both sides.


  • 2x-30+30=-7+30

  • 2x=23

Step 4: Divide both sides by 2.


  • 2x/2 = 23/2

  • x = 23/2 = 11.5

Therefore, x = 23/2 or 11.5.
