Kua tāruatia ki te papatopenga
-14y-147+2y=-19
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te -2y-21.
-12y-147=-19
Pahekotia te -14y me 2y, ka -12y.
-12y=-19+147
Me tāpiri te 147 ki ngā taha e rua.
-12y=128
Tāpirihia te -19 ki te 147, ka 128.
y=\frac{128}{-12}
Whakawehea ngā taha e rua ki te -12.
y=-\frac{32}{3}
Whakahekea te hautanga \frac{128}{-12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
