x=suma initiala
26%x=26x/100
26x/100+440+30x/100=x
26x+44000+30x=100x
44x=44000
x=1000 lei suma initiala
26%x=26x/100
26x/100+440+30x/100=x
26x+44000+30x=100x
44x=44000
x=1000 lei suma initiala
x- (26x/100 +440)=30/100
100x-26x- 44000= 30
74x-30x=44000
44x=44000 |÷44
x=1000 lei
100x-26x- 44000= 30
74x-30x=44000
44x=44000 |÷44
x=1000 lei
