5y+2y-12=4\left(y+2\right)-3
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te y-6.
7y-12=4\left(y+2\right)-3
Pahekotia te 5y me 2y, ka 7y.
7y-12=4y+8-3
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te y+2.
7y-12=4y+5
Tangohia te 3 i te 8, ka 5.
7y-12-4y=5
Tangohia te 4y mai i ngā taha e rua.
3y-12=5
Pahekotia te 7y me -4y, ka 3y.
3y=5+12
Me tāpiri te 12 ki ngā taha e rua.
3y=17
Tāpirihia te 5 ki te 12, ka 17.
y=\frac{17}{3}
Whakawehea ngā taha e rua ki te 3.
