Linear Equation
5 raruraru e ōrite ana ki:
\frac { 2 x } { x + 3 } + 1 = \frac { 7 } { 2 x + 6 }
Tohaina
Kua tāruatia ki te papatopenga
2\times 2x+2\left(x+3\right)=7
Tē taea kia ōrite te tāupe x ki -3 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2\left(x+3\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+3,2x+6.
4x+2\left(x+3\right)=7
Whakareatia te 2 ki te 2, ka 4.
4x+2x+6=7
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+3.
6x+6=7
Pahekotia te 4x me 2x, ka 6x.
6x=7-6
Tangohia te 6 mai i ngā taha e rua.
6x=1
Tangohia te 6 i te 7, ka 1.
x=\frac{1}{6}
Whakawehea ngā taha e rua ki te 6.
