Answer:

x = 4

Step-by-step 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.

  • [tex]15x+3x-15=27-15[/tex]
  • [tex]3x=12[/tex]

Step 2: Divide both sides by 3.

  • [tex]3x/3 = 12/3[/tex]
  • [tex]x=4[/tex]

Step 3: Check if solution is correct.

  • [tex]15+3(4)=27[/tex]
  • [tex]15+12=27[/tex]
  • [tex]27[/tex]

Solution:

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.
