Kua tāruatia ki te papatopenga
5x=7\left(6-x\right)
Me whakarea ngā taha e rua o te whārite ki te 35, arā, te tauraro pātahi he tino iti rawa te kitea o 7,5.
5x=42-7x
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te 6-x.
5x+7x=42
Me tāpiri te 7x ki ngā taha e rua.
12x=42
Pahekotia te 5x me 7x, ka 12x.
x=\frac{42}{12}
Whakawehea ngā taha e rua ki te 12.
x=\frac{7}{2}
Whakahekea te hautanga \frac{42}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.
