A carpenter had two pieces of lumber that totaled 55 feet in length. The shorter piece was 12 feet
dimulka [17.4K]

The equation to find the length of the longer piece is

x- 12 = 55

Step-by-step explanation:

  • A carpenter had two pieces of lumber that totaled in length = 55 feet
  • The shorter piece than the longer piece has length of which is = 12 feet
  • The longer piece is denoted as= x
  • Find x = ?
  • The equation can be formed to find the value of x as,
  • Longer piece (x) ₋ shorter piece (12) = total length (55)
  • Therefore, x ₋ 12 = 55
  • the above equation states that
  • if you subtract the shorter piece from the total length of the you will get the length of the longer piece.
  • therefore,
  • if you shift the value of shorter length on the right hand side, you can find the value of x
  • so, x= 55 ₋ 12
  • value of x = 43
  • therefore, the length of the longer piece is 43 feet long.
