Explicație pas cu pas:
8x50cg+6x250dg=400cg+1500dg=4g+150g=154g
20000g:4-20x1500dg=5000g-30000dg=50hg-30hg=20hg
8q-(2x650dag+4x750g)50=800kg-(1300dag+3000g)50=
=800kg-(13kg+3kg)50=800kg-16kgx50=800kg-800kg=0kg
9t+[500q-(500kg-5x800hg)x9]=9000kg+[50000kg-(500kg-4000hg)x9]=
=9000kg+[50000kg-(500kg-40kg)x9]=
=9000kg+(50000kg-460kgx9)=9000kg+(50000kg-4140kg)=
=54860kg=548,6q
