5 raruraru e ōrite ana ki:
3 \left( 1-5x \right) -2 \left( 2-6x \right) +2x = 0
Tohaina
Kua tāruatia ki te papatopenga
3-15x-2\left(2-6x\right)+2x=0
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 1-5x.
3-15x-4+12x+2x=0
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 2-6x.
-1-15x+12x+2x=0
Tangohia te 4 i te 3, ka -1.
-1-3x+2x=0
Pahekotia te -15x me 12x, ka -3x.
-1-x=0
Pahekotia te -3x me 2x, ka -x.
-x=1
Me tāpiri te 1 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=-1
Me whakarea ngā taha e rua ki te -1.
