0.03x=0.027-0.15y
Tangohia te 0.15y mai i ngā taha e rua.
0.03x=-\frac{3y}{20}+0.027
He hanga arowhānui tō te whārite.
\frac{0.03x}{0.03}=\frac{-\frac{3y}{20}+0.027}{0.03}
Whakawehea ngā taha e rua o te whārite ki te 0.03, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{-\frac{3y}{20}+0.027}{0.03}
Mā te whakawehe ki te 0.03 ka wetekia te whakareanga ki te 0.03.
x=\frac{9}{10}-5y
Whakawehe 0.027-\frac{3y}{20} ki te 0.03 mā te whakarea 0.027-\frac{3y}{20} ki te tau huripoki o 0.03.
0.15y=0.027-0.03x
Tangohia te 0.03x mai i ngā taha e rua.
0.15y=-\frac{3x}{100}+0.027
He hanga arowhānui tō te whārite.
\frac{0.15y}{0.15}=\frac{-\frac{3x}{100}+0.027}{0.15}
Whakawehea ngā taha e rua o te whārite ki te 0.15, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
y=\frac{-\frac{3x}{100}+0.027}{0.15}
Mā te whakawehe ki te 0.15 ka wetekia te whakareanga ki te 0.15.
y=-\frac{x}{5}+\frac{9}{50}
Whakawehe 0.027-\frac{3x}{100} ki te 0.15 mā te whakarea 0.027-\frac{3x}{100} ki te tau huripoki o 0.15.
