2. a 121 cm board is cut into two pieces. if one piece is 35 cm shorter than the other, how long are the two pieces?
.
x=length of shorter piece; x+35cm=longer piece
x+x+35cm=121cm
2x=86cm
x=43cm
ANSWER 1: The shorter piece is 43 centimeters.
.
x=35cm=43cm+35cm=78cm
ANSWER 2: The longer piece is 78 centimeters.

(x+2)+(3x+5)+(5x)=70
9x+7=70
9x=63
x=7
Intermediate side=3x+5=3(7)+5=21+5=26
