Kua tāruatia ki te papatopenga
-3mx+4=x
Me tāpiri te x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
-3mx=x-4
Tangohia te 4 mai i ngā taha e rua.
\left(-3x\right)m=x-4
He hanga arowhānui tō te whārite.
\frac{\left(-3x\right)m}{-3x}=\frac{x-4}{-3x}
Whakawehea ngā taha e rua ki te -3x.
m=\frac{x-4}{-3x}
Mā te whakawehe ki te -3x ka wetekia te whakareanga ki te -3x.
m=-\frac{1}{3}+\frac{4}{3x}
Whakawehe x-4 ki te -3x.
-3mx-x=-4
Tangohia te 4 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\left(-3m-1\right)x=-4
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(-3m-1\right)x}{-3m-1}=-\frac{4}{-3m-1}
Whakawehea ngā taha e rua ki te -3m-1.
x=-\frac{4}{-3m-1}
Mā te whakawehe ki te -3m-1 ka wetekia te whakareanga ki te -3m-1.
x=\frac{4}{3m+1}
Whakawehe -4 ki te -3m-1.
