Kua tāruatia ki te papatopenga
-2zx+5=0
Pahekotia te zx me -3zx, ka -2zx.
-2zx=-5
Tangohia te 5 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\left(-2z\right)x=-5
He hanga arowhānui tō te whārite.
\frac{\left(-2z\right)x}{-2z}=-\frac{5}{-2z}
Whakawehea ngā taha e rua ki te -2z.
x=-\frac{5}{-2z}
Mā te whakawehe ki te -2z ka wetekia te whakareanga ki te -2z.
x=\frac{5}{2z}
Whakawehe -5 ki te -2z.
-2zx+5=0
Pahekotia te zx me -3zx, ka -2zx.
-2zx=-5
Tangohia te 5 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\left(-2x\right)z=-5
He hanga arowhānui tō te whārite.
\frac{\left(-2x\right)z}{-2x}=-\frac{5}{-2x}
Whakawehea ngā taha e rua ki te -2x.
z=-\frac{5}{-2x}
Mā te whakawehe ki te -2x ka wetekia te whakareanga ki te -2x.
z=\frac{5}{2x}
Whakawehe -5 ki te -2x.
