Kua tāruatia ki te papatopenga
2x-2=5\left(x-2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-1.
2x-2=5x-10
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-2.
2x-2-5x=-10
Tangohia te 5x mai i ngā taha e rua.
-3x-2=-10
Pahekotia te 2x me -5x, ka -3x.
-3x=-10+2
Me tāpiri te 2 ki ngā taha e rua.
-3x=-8
Tāpirihia te -10 ki te 2, ka -8.
x=\frac{-8}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{8}{3}
Ka taea te hautanga \frac{-8}{-3} te whakamāmā ki te \frac{8}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
