A 54-inch board is cut into two pieces. One piece is two times the length of the other. Find the length
of the shorter piece.

The shorter piece is how many inches long?

18

Step-by-step explanation:

if the board was cut by 2, and one is 2 times the size of the other

54/3= 18

if one side is 18 (the short side)

and the long side is 36 (18x2=36)

36+18= 54

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
