5\left(y-4\right)=4\left(y+1\right)
Me whakarea ngā taha e rua o te whārite ki te 20, arā, te tauraro pātahi he tino iti rawa te kitea o 4,5.
5y-20=4\left(y+1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te y-4.
5y-20=4y+4
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te y+1.
5y-20-4y=4
Tangohia te 4y mai i ngā taha e rua.
y-20=4
Pahekotia te 5y me -4y, ka y.
y=4+20
Me tāpiri te 20 ki ngā taha e rua.
y=24
Tāpirihia te 4 ki te 20, ka 24.
