5 raruraru e ōrite ana ki:
0.05 \left( 2000+2x \right) = 0.04 \left( 2500-6x \right)
Tohaina
Kua tāruatia ki te papatopenga
100+0.1x=0.04\left(2500-6x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 0.05 ki te 2000+2x.
100+0.1x=100-0.24x
Whakamahia te āhuatanga tohatoha hei whakarea te 0.04 ki te 2500-6x.
100+0.1x+0.24x=100
Me tāpiri te 0.24x ki ngā taha e rua.
100+0.34x=100
Pahekotia te 0.1x me 0.24x, ka 0.34x.
0.34x=100-100
Tangohia te 100 mai i ngā taha e rua.
0.34x=0
Tangohia te 100 i te 100, ka 0.
x=0
He ōrite te hua o ngā tau e rua ki 0 ina 0 tētahi o rāua te iti rawa. Tātemea kāore te 0.34 e ōrite ki 0, me ōrite pū te x ki 0.
