Linear Equation
2y+1=13-y
Tohaina
Kua tāruatia ki te papatopenga
2y+1+y=13
Me tāpiri te y ki ngā taha e rua.
3y+1=13
Pahekotia te 2y me y, ka 3y.
3y=13-1
Tangohia te 1 mai i ngā taha e rua.
3y=12
Tangohia te 1 i te 13, ka 12.
y=\frac{12}{3}
Whakawehea ngā taha e rua ki te 3.
y=4
Whakawehea te 12 ki te 3, kia riro ko 4.
