the value of x?

Answer 1

Note that:

• 5 + x + 5 + x + 5 + x = 27

Simplify the equation and solve for x.

• 5 + x + 5 + x + 5 + x = 27
• => 15 + 3x = 27
• => 3x = 27 - 15
• => 3x = 12
• => x = 4

The value of x is 4.

Answer 2

x = 4

Explanation:

We can write this scale as 15 + 3x = 27.

• We wrote 15 because there are three five's, thus making 15
• We wrote 3x because there are three x's

Step 1: Subtract 15 from both sides.

• 
  `15x+3x-15=27-15`
• 
  `3x=12`

Step 2: Divide both sides by 3.

• 
  `3x/3 = 12/3`
• 
  `x=4`

Step 3: Check if solution is correct.

• 
  `15+3(4)=27`
• 
  `15+12=27`
• 
  `27`
