47x-141=5x-9
Whakamahia te āhuatanga tohatoha hei whakarea te 47 ki te x-3.
47x-141-5x=-9
Tangohia te 5x mai i ngā taha e rua.
42x-141=-9
Pahekotia te 47x me -5x, ka 42x.
42x=-9+141
Me tāpiri te 141 ki ngā taha e rua.
42x=132
Tāpirihia te -9 ki te 141, ka 132.
x=\frac{132}{42}
Whakawehea ngā taha e rua ki te 42.
x=\frac{22}{7}
Whakahekea te hautanga \frac{132}{42} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.
