Explicație pas cu pas:

a)

x=14 cm 8 mm - 8 cm 9mm

x=13 cm 18 mm - 8cm 9mm

x=6 cm 9 mm

b)

x= 6 cm 7 mm + 14 cm 8mm

x= 20 cm 15 mm

x= 21 cm 5 mm

c)

x+2/3x = 12 cm 5mm

5/3x =36/3 cm 15/3 mm

5x = 36 cm 15 mm

5x= 35 cm 25 mm

x= 7 cm 5 mm

d)

x= 1/3x + 11cm 2 mm

x - 1/3x = 11 cm 2mm

2/3 x = 33/3 cm 6/3 mm
