Kua tāruatia ki te papatopenga
\sqrt{3}\left(x+0\right)=28-x
Whakareatia te 0 ki te 2, ka 0.
\sqrt{3}x=28-x
Ko te tau i tāpiria he kore ka hua koia tonu.
\sqrt{3}x+x=28
Me tāpiri te x ki ngā taha e rua.
\left(\sqrt{3}+1\right)x=28
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(\sqrt{3}+1\right)x}{\sqrt{3}+1}=\frac{28}{\sqrt{3}+1}
Whakawehea ngā taha e rua ki te \sqrt{3}+1.
x=\frac{28}{\sqrt{3}+1}
Mā te whakawehe ki te \sqrt{3}+1 ka wetekia te whakareanga ki te \sqrt{3}+1.
x=14\sqrt{3}-14
Whakawehe 28 ki te \sqrt{3}+1.
