Tohaina
Kua tāruatia ki te papatopenga
4x-4+3\left(y-1\right)=15
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-1.
4x-4+3y-3=15
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te y-1.
4x-7+3y=15
Tangohia te 3 i te -4, ka -7.
4x+3y=15+7
Me tāpiri te 7 ki ngā taha e rua.
4x+3y=22
Tāpirihia te 15 ki te 7, ka 22.
4x=22-3y
Tangohia te 3y mai i ngā taha e rua.
\frac{4x}{4}=\frac{22-3y}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{22-3y}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=-\frac{3y}{4}+\frac{11}{2}
Whakawehe 22-3y ki te 4.
4x-4+3\left(y-1\right)=15
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-1.
4x-4+3y-3=15
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te y-1.
4x-7+3y=15
Tangohia te 3 i te -4, ka -7.
-7+3y=15-4x
Tangohia te 4x mai i ngā taha e rua.
3y=15-4x+7
Me tāpiri te 7 ki ngā taha e rua.
3y=22-4x
Tāpirihia te 15 ki te 7, ka 22.
\frac{3y}{3}=\frac{22-4x}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{22-4x}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
