Kua tāruatia ki te papatopenga
20+2x=3-2x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 10+x.
20+2x+2x=3
Me tāpiri te 2x ki ngā taha e rua.
20+4x=3
Pahekotia te 2x me 2x, ka 4x.
4x=3-20
Tangohia te 20 mai i ngā taha e rua.
4x=-17
Tangohia te 20 i te 3, ka -17.
x=\frac{-17}{4}
Whakawehea ngā taha e rua ki te 4.
x=-\frac{17}{4}
Ka taea te hautanga \frac{-17}{4} te tuhi anō ko -\frac{17}{4} mā te tango i te tohu tōraro.
