3x-2=A-2-\left(-4\right)-4
Whakareatia te 2 ki te -2, ka -4.
3x-2=A-2+4-4
Ko te tauaro o -4 ko 4.
3x-2=A+2-4
Tāpirihia te -2 ki te 4, ka 2.
3x-2=A-2
Tangohia te 4 i te 2, ka -2.
A-2=3x-2
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
A=3x-2+2
Me tāpiri te 2 ki ngā taha e rua.
A=3x
Tāpirihia te -2 ki te 2, ka 0.
3x-2=A-2-\left(-4\right)-4
Whakareatia te 2 ki te -2, ka -4.
3x-2=A-2+4-4
Ko te tauaro o -4 ko 4.
3x-2=A+2-4
Tāpirihia te -2 ki te 4, ka 2.
3x-2=A-2
Tangohia te 4 i te 2, ka -2.
3x=A-2+2
Me tāpiri te 2 ki ngā taha e rua.
3x=A
Tāpirihia te -2 ki te 2, ka 0.
\frac{3x}{3}=\frac{A}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{A}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
