Linear Equation
5 raruraru e ōrite ana ki:
\frac { 2 v + 6 } { 5 } + \frac { 3 v + 6 } { 4 } = 5
Tohaina
Kua tāruatia ki te papatopenga
4\left(2v+6\right)+5\left(3v+6\right)=100
Me whakarea ngā taha e rua o te whārite ki te 20, arā, te tauraro pātahi he tino iti rawa te kitea o 5,4.
8v+24+5\left(3v+6\right)=100
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2v+6.
8v+24+15v+30=100
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 3v+6.
23v+24+30=100
Pahekotia te 8v me 15v, ka 23v.
23v+54=100
Tāpirihia te 24 ki te 30, ka 54.
23v=100-54
Tangohia te 54 mai i ngā taha e rua.
23v=46
Tangohia te 54 i te 100, ka 46.
v=\frac{46}{23}
Whakawehea ngā taha e rua ki te 23.
v=2
Whakawehea te 46 ki te 23, kia riro ko 2.
