-24x-3x\left(-15\right)+k=0
Whakareatia te 4 ki te -6, ka -24.
-24x-\left(-45x\right)+k=0
Whakareatia te 3 ki te -15, ka -45.
-24x+45x+k=0
Ko te tauaro o -45x ko 45x.
21x+k=0
Pahekotia te -24x me 45x, ka 21x.
k=-21x
Tangohia te 21x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-24x-3x\left(-15\right)+k=0
Whakareatia te 4 ki te -6, ka -24.
-24x-\left(-45x\right)+k=0
Whakareatia te 3 ki te -15, ka -45.
-24x+45x+k=0
Ko te tauaro o -45x ko 45x.
21x+k=0
Pahekotia te -24x me 45x, ka 21x.
21x=-k
Tangohia te k mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{21x}{21}=-\frac{k}{21}
Whakawehea ngā taha e rua ki te 21.
x=-\frac{k}{21}
Mā te whakawehe ki te 21 ka wetekia te whakareanga ki te 21.
