Kua tāruatia ki te papatopenga
x+2=3\left(x-3\right)
Me whakarea ngā taha e rua o te whārite ki te 9, arā, te tauraro pātahi he tino iti rawa te kitea o 9,3.
x+2=3x-9
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-3.
x+2-3x=-9
Tangohia te 3x mai i ngā taha e rua.
-2x+2=-9
Pahekotia te x me -3x, ka -2x.
-2x=-9-2
Tangohia te 2 mai i ngā taha e rua.
-2x=-11
Tangohia te 2 i te -9, ka -11.
x=\frac{-11}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{11}{2}
Ka taea te hautanga \frac{-11}{-2} te whakamāmā ki te \frac{11}{2} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
