Kua tāruatia ki te papatopenga
0.5x=36-0.2y
Tangohia te 0.2y mai i ngā taha e rua.
0.5x=-\frac{y}{5}+36
He hanga arowhānui tō te whārite.
\frac{0.5x}{0.5}=\frac{-\frac{y}{5}+36}{0.5}
Me whakarea ngā taha e rua ki te 2.
x=\frac{-\frac{y}{5}+36}{0.5}
Mā te whakawehe ki te 0.5 ka wetekia te whakareanga ki te 0.5.
x=-\frac{2y}{5}+72
Whakawehe 36-\frac{y}{5} ki te 0.5 mā te whakarea 36-\frac{y}{5} ki te tau huripoki o 0.5.
0.2y=36-0.5x
Tangohia te 0.5x mai i ngā taha e rua.
0.2y=-\frac{x}{2}+36
He hanga arowhānui tō te whārite.
\frac{0.2y}{0.2}=\frac{-\frac{x}{2}+36}{0.2}
Me whakarea ngā taha e rua ki te 5.
y=\frac{-\frac{x}{2}+36}{0.2}
Mā te whakawehe ki te 0.2 ka wetekia te whakareanga ki te 0.2.
y=-\frac{5x}{2}+180
Whakawehe 36-\frac{x}{2} ki te 0.2 mā te whakarea 36-\frac{x}{2} ki te tau huripoki o 0.2.
