Linear Equation
2+3(x-3)=14
Tohaina
Kua tāruatia ki te papatopenga
2+3x-9=14
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-3.
-7+3x=14
Tangohia te 9 i te 2, ka -7.
3x=14+7
Me tāpiri te 7 ki ngā taha e rua.
3x=21
Tāpirihia te 14 ki te 7, ka 21.
x=\frac{21}{3}
Whakawehea ngā taha e rua ki te 3.
x=7
Whakawehea te 21 ki te 3, kia riro ko 7.
