a) x=14cm 8mm-8cm 9mm
x=13cm 18mm-8cm 9cm
x=5cm 9mm=59mm
b) x= 6cm 7mm+14cm 8mm
x=20cm 15 mm=215mm
c) 2x/3+x=125mm
2x+3x/3=125mm
5x/3=125mm
x=3×125mm/5
x=75mm
d) x=x/3+112mm aducem la același numitor
3x/3=x+336mm/3 eliminăm numitorul
3x=x+336mm
3x-x=336mm
2x=336mm
x=336mm/2
x=168mm
Sper că te-am ajutat! °∪°
