5y+5a+3\left(y-b\right)=8y-19
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te y+a.
5y+5a+3y-3b=8y-19
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te y-b.
8y+5a-3b=8y-19
Pahekotia te 5y me 3y, ka 8y.
5a-3b=8y-19-8y
Tangohia te 8y mai i ngā taha e rua.
5a-3b=-19
Pahekotia te 8y me -8y, ka 0.
5a=-19+3b
Me tāpiri te 3b ki ngā taha e rua.
5a=3b-19
He hanga arowhānui tō te whārite.
\frac{5a}{5}=\frac{3b-19}{5}
Whakawehea ngā taha e rua ki te 5.
a=\frac{3b-19}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
5y+5a+3\left(y-b\right)=8y-19
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te y+a.
5y+5a+3y-3b=8y-19
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te y-b.
8y+5a-3b=8y-19
Pahekotia te 5y me 3y, ka 8y.
5a-3b=8y-19-8y
Tangohia te 8y mai i ngā taha e rua.
5a-3b=-19
Pahekotia te 8y me -8y, ka 0.
-3b=-19-5a
Tangohia te 5a mai i ngā taha e rua.
-3b=-5a-19
He hanga arowhānui tō te whārite.
\frac{-3b}{-3}=\frac{-5a-19}{-3}
Whakawehea ngā taha e rua ki te -3.
b=\frac{-5a-19}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
b=\frac{5a+19}{3}
Whakawehe -19-5a ki te -3.
