5x+4x-2=3x-14
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x-1.
9x-2=3x-14
Pahekotia te 5x me 4x, ka 9x.
9x-2-3x=-14
Tangohia te 3x mai i ngā taha e rua.
6x-2=-14
Pahekotia te 9x me -3x, ka 6x.
6x=-14+2
Me tāpiri te 2 ki ngā taha e rua.
6x=-12
Tāpirihia te -14 ki te 2, ka -12.
x=\frac{-12}{6}
Whakawehea ngā taha e rua ki te 6.
x=-2
Whakawehea te -12 ki te 6, kia riro ko -2.
