5 raruraru e ōrite ana ki:
\frac{ x-3 }{ 5 } - \frac{ x-2 }{ 7 } = \frac{ 13 }{ 2 }
Tohaina
Kua tāruatia ki te papatopenga
14\left(x-3\right)-10\left(x-2\right)=455
Me whakarea ngā taha e rua o te whārite ki te 70, arā, te tauraro pātahi he tino iti rawa te kitea o 5,7,2.
14x-42-10\left(x-2\right)=455
Whakamahia te āhuatanga tohatoha hei whakarea te 14 ki te x-3.
14x-42-10x+20=455
Whakamahia te āhuatanga tohatoha hei whakarea te -10 ki te x-2.
4x-42+20=455
Pahekotia te 14x me -10x, ka 4x.
4x-22=455
Tāpirihia te -42 ki te 20, ka -22.
4x=455+22
Me tāpiri te 22 ki ngā taha e rua.
4x=477
Tāpirihia te 455 ki te 22, ka 477.
x=\frac{477}{4}
Whakawehea ngā taha e rua ki te 4.
