Kua tāruatia ki te papatopenga
x+8=4\left(x-2\right)
Whakareatia ngā taha e rua o te whārite ki te 2.
x+8=4x-8
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-2.
x+8-4x=-8
Tangohia te 4x mai i ngā taha e rua.
-3x+8=-8
Pahekotia te x me -4x, ka -3x.
-3x=-8-8
Tangohia te 8 mai i ngā taha e rua.
-3x=-16
Tangohia te 8 i te -8, ka -16.
x=\frac{-16}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{16}{3}
Ka taea te hautanga \frac{-16}{-3} te whakamāmā ki te \frac{16}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
