6\times 3x-42x=7y-14y
Me whakarea ngā taha e rua o te whārite ki te 42, arā, te tauraro pātahi he tino iti rawa te kitea o 7,6,3.
18x-42x=7y-14y
Whakareatia te 6 ki te 3, ka 18.
-24x=7y-14y
Pahekotia te 18x me -42x, ka -24x.
-24x=-7y
Pahekotia te 7y me -14y, ka -7y.
\frac{-24x}{-24}=-\frac{7y}{-24}
Whakawehea ngā taha e rua ki te -24.
x=-\frac{7y}{-24}
Mā te whakawehe ki te -24 ka wetekia te whakareanga ki te -24.
x=\frac{7y}{24}
Whakawehe -7y ki te -24.
6\times 3x-42x=7y-14y
Me whakarea ngā taha e rua o te whārite ki te 42, arā, te tauraro pātahi he tino iti rawa te kitea o 7,6,3.
18x-42x=7y-14y
Whakareatia te 6 ki te 3, ka 18.
-24x=7y-14y
Pahekotia te 18x me -42x, ka -24x.
-24x=-7y
Pahekotia te 7y me -14y, ka -7y.
-7y=-24x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{-7y}{-7}=-\frac{24x}{-7}
Whakawehea ngā taha e rua ki te -7.
y=-\frac{24x}{-7}
Mā te whakawehe ki te -7 ka wetekia te whakareanga ki te -7.
y=\frac{24x}{7}
Whakawehe -24x ki te -7.
