Linear Equation
25.8 = 2 x - 5
Tohaina
Kua tāruatia ki te papatopenga
2x-5=25.8
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2x=25.8+5
Me tāpiri te 5 ki ngā taha e rua.
2x=30.8
Tāpirihia te 25.8 ki te 5, ka 30.8.
x=\frac{30.8}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{308}{20}
Whakarohaina te \frac{30.8}{2} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{77}{5}
Whakahekea te hautanga \frac{308}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
