5 raruraru e ōrite ana ki:
x + \frac { 3 x + 2 } { 2 } = \frac { 1 + x } { 4 }
Tohaina
Kua tāruatia ki te papatopenga
4x+2\left(3x+2\right)=1+x
Me whakarea ngā taha e rua o te whārite ki te 4, arā, te tauraro pātahi he tino iti rawa te kitea o 2,4.
4x+6x+4=1+x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3x+2.
10x+4=1+x
Pahekotia te 4x me 6x, ka 10x.
10x+4-x=1
Tangohia te x mai i ngā taha e rua.
9x+4=1
Pahekotia te 10x me -x, ka 9x.
9x=1-4
Tangohia te 4 mai i ngā taha e rua.
9x=-3
Tangohia te 4 i te 1, ka -3.
x=\frac{-3}{9}
Whakawehea ngā taha e rua ki te 9.
x=-\frac{1}{3}
Whakahekea te hautanga \frac{-3}{9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
