Linear Equation
15x+2y-30=0
Tohaina
Kua tāruatia ki te papatopenga
15x-30=-2y
Tangohia te 2y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
15x=-2y+30
Me tāpiri te 30 ki ngā taha e rua.
15x=30-2y
He hanga arowhānui tō te whārite.
\frac{15x}{15}=\frac{30-2y}{15}
Whakawehea ngā taha e rua ki te 15.
x=\frac{30-2y}{15}
Mā te whakawehe ki te 15 ka wetekia te whakareanga ki te 15.
x=-\frac{2y}{15}+2
Whakawehe -2y+30 ki te 15.
2y-30=-15x
Tangohia te 15x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2y=-15x+30
Me tāpiri te 30 ki ngā taha e rua.
2y=30-15x
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{30-15x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{30-15x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=-\frac{15x}{2}+15
Whakawehe -15x+30 ki te 2.
