Kua tāruatia ki te papatopenga
2x+14-x=1-\left(x+38\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+7.
x+14=1-\left(x+38\right)
Pahekotia te 2x me -x, ka x.
x+14=1-x-38
Hei kimi i te tauaro o x+38, kimihia te tauaro o ia taurangi.
x+14=-37-x
Tangohia te 38 i te 1, ka -37.
x+14+x=-37
Me tāpiri te x ki ngā taha e rua.
2x+14=-37
Pahekotia te x me x, ka 2x.
2x=-37-14
Tangohia te 14 mai i ngā taha e rua.
2x=-51
Tangohia te 14 i te -37, ka -51.
x=\frac{-51}{2}
Whakawehea ngā taha e rua ki te 2.
x=-\frac{51}{2}
Ka taea te hautanga \frac{-51}{2} te tuhi anō ko -\frac{51}{2} mā te tango i te tohu tōraro.
