Kua tāruatia ki te papatopenga
4x=1
Whakaarohia te whārite tuatahi. Me tāpiri te 1 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{1}{4}
Whakawehea ngā taha e rua ki te 4.
y=\left(4\times \frac{1}{4}-1\right)\left(\frac{1}{4}+5\right)-\left(4\times \frac{1}{4}-1\right)\left(2\times \frac{1}{4}+3\right)
Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
y=\left(1-1\right)\left(\frac{1}{4}+5\right)-\left(4\times \frac{1}{4}-1\right)\left(2\times \frac{1}{4}+3\right)
Whakareatia te 4 ki te \frac{1}{4}, ka 1.
y=0\left(\frac{1}{4}+5\right)-\left(4\times \frac{1}{4}-1\right)\left(2\times \frac{1}{4}+3\right)
Tangohia te 1 i te 1, ka 0.
y=0\times \frac{21}{4}-\left(4\times \frac{1}{4}-1\right)\left(2\times \frac{1}{4}+3\right)
Tāpirihia te \frac{1}{4} ki te 5, ka \frac{21}{4}.
y=0-\left(4\times \frac{1}{4}-1\right)\left(2\times \frac{1}{4}+3\right)
Whakareatia te 0 ki te \frac{21}{4}, ka 0.
y=0-\left(1-1\right)\left(2\times \frac{1}{4}+3\right)
Whakareatia te 4 ki te \frac{1}{4}, ka 1.
y=0-0\left(2\times \frac{1}{4}+3\right)
Tangohia te 1 i te 1, ka 0.
y=0-0\left(\frac{1}{2}+3\right)
Whakareatia te 2 ki te \frac{1}{4}, ka \frac{1}{2}.
y=0-0\times \frac{7}{2}
Tāpirihia te \frac{1}{2} ki te 3, ka \frac{7}{2}.
y=0-0
Whakareatia te 0 ki te \frac{7}{2}, ka 0.
y=0
Mā te tango i te 0 i a ia ake anō ka toe ko te 0.
z=0
Whakaarohia te whārite tuatoru. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
a=0
Whakaarohia te whārite tuawhā. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
b=0
Whakaarohia te whārite tuarima. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
c=0
Whakaarohia te whārite (6). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
x=\frac{1}{4} y=0 z=0 a=0 b=0 c=0
Kua oti te pūnaha te whakatau.
