Linear Equation
7x-3y=1
Tohaina
Kua tāruatia ki te papatopenga
7x=1+3y
Me tāpiri te 3y ki ngā taha e rua.
7x=3y+1
He hanga arowhānui tō te whārite.
\frac{7x}{7}=\frac{3y+1}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{3y+1}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
-3y=1-7x
Tangohia te 7x mai i ngā taha e rua.
\frac{-3y}{-3}=\frac{1-7x}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{1-7x}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{7x-1}{3}
Whakawehe 1-7x ki te -3.
