Graph
Tohaina
Kua tāruatia ki te papatopenga
5\sqrt{3}x+2x=40
Me tāpiri te 2x ki ngā taha e rua.
\left(5\sqrt{3}+2\right)x=40
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(5\sqrt{3}+2\right)x}{5\sqrt{3}+2}=\frac{40}{5\sqrt{3}+2}
Whakawehea ngā taha e rua ki te 5\sqrt{3}+2.
x=\frac{40}{5\sqrt{3}+2}
Mā te whakawehe ki te 5\sqrt{3}+2 ka wetekia te whakareanga ki te 5\sqrt{3}+2.
x=\frac{200\sqrt{3}-80}{71}
Whakawehe 40 ki te 5\sqrt{3}+2.
