5 raruraru e ōrite ana ki:
\frac { ( x + 2 ) } { 4 } = \frac { ( 3 x + 4 ) } { 2 }
Tohaina
Kua tāruatia ki te papatopenga
x+2=2\left(3x+4\right)
Me whakarea ngā taha e rua o te whārite ki te 4, arā, te tauraro pātahi he tino iti rawa te kitea o 4,2.
x+2=6x+8
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3x+4.
x+2-6x=8
Tangohia te 6x mai i ngā taha e rua.
-5x+2=8
Pahekotia te x me -6x, ka -5x.
-5x=8-2
Tangohia te 2 mai i ngā taha e rua.
-5x=6
Tangohia te 2 i te 8, ka 6.
x=\frac{6}{-5}
Whakawehea ngā taha e rua ki te -5.
x=-\frac{6}{5}
Ka taea te hautanga \frac{6}{-5} te tuhi anō ko -\frac{6}{5} mā te tango i te tohu tōraro.
