a+b=23t---> a+b=2300kg
a=b+5q--> a=b+50kg
b+50kg+b=2300kg
2b=2250kg
b=1125kg
a=1175kg

zahar total=23t=23*1000kg=23000kg
a=primul transport
b=al doilea transport
a+b=23000kg
5q=100kg*5=500kg
a=5q+b
a=500kg+b
500kg+b+b=23000kg
500kg+2b=23000kg/-500kg
2b=22500/÷2
b=11250kg⇒
a=500kg+b
a=500kg+11250kg
a=11750kg
