Kua tāruatia ki te papatopenga
-21x=-x+3-\left(x+2\right)+10
Pahekotia te -15x me -6x, ka -21x.
-21x=-x+3-x-2+10
Hei kimi i te tauaro o x+2, kimihia te tauaro o ia taurangi.
-21x=-x+1-x+10
Tangohia te 2 i te 3, ka 1.
-21x=-x+11-x
Tāpirihia te 1 ki te 10, ka 11.
-21x+x=11-x
Me tāpiri te x ki ngā taha e rua.
-20x=11-x
Pahekotia te -21x me x, ka -20x.
-20x+x=11
Me tāpiri te x ki ngā taha e rua.
-19x=11
Pahekotia te -20x me x, ka -19x.
x=\frac{11}{-19}
Whakawehea ngā taha e rua ki te -19.
x=-\frac{11}{19}
Ka taea te hautanga \frac{11}{-19} te tuhi anō ko -\frac{11}{19} mā te tango i te tohu tōraro.
