Kua tāruatia ki te papatopenga
x+3x-3=6-4\left(2x-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-1.
4x-3=6-4\left(2x-3\right)
Pahekotia te x me 3x, ka 4x.
4x-3=6-8x+12
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te 2x-3.
4x-3=18-8x
Tāpirihia te 6 ki te 12, ka 18.
4x-3+8x=18
Me tāpiri te 8x ki ngā taha e rua.
12x-3=18
Pahekotia te 4x me 8x, ka 12x.
12x=18+3
Me tāpiri te 3 ki ngā taha e rua.
12x=21
Tāpirihia te 18 ki te 3, ka 21.
x=\frac{21}{12}
Whakawehea ngā taha e rua ki te 12.
x=\frac{7}{4}
Whakahekea te hautanga \frac{21}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
