0.09x=510-0.04y
Tangohia te 0.04y mai i ngā taha e rua.
0.09x=-\frac{y}{25}+510
He hanga arowhānui tō te whārite.
\frac{0.09x}{0.09}=\frac{-\frac{y}{25}+510}{0.09}
Whakawehea ngā taha e rua o te whārite ki te 0.09, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{-\frac{y}{25}+510}{0.09}
Mā te whakawehe ki te 0.09 ka wetekia te whakareanga ki te 0.09.
x=-\frac{4y}{9}+\frac{17000}{3}
Whakawehe 510-\frac{y}{25} ki te 0.09 mā te whakarea 510-\frac{y}{25} ki te tau huripoki o 0.09.
0.04y=510-0.09x
Tangohia te 0.09x mai i ngā taha e rua.
0.04y=-\frac{9x}{100}+510
He hanga arowhānui tō te whārite.
\frac{0.04y}{0.04}=\frac{-\frac{9x}{100}+510}{0.04}
Me whakarea ngā taha e rua ki te 25.
y=\frac{-\frac{9x}{100}+510}{0.04}
Mā te whakawehe ki te 0.04 ka wetekia te whakareanga ki te 0.04.
y=-\frac{9x}{4}+12750
Whakawehe 510-\frac{9x}{100} ki te 0.04 mā te whakarea 510-\frac{9x}{100} ki te tau huripoki o 0.04.
