-10\left(x-1\right)=-5-6\left(x-1\right)
Me whakarea ngā taha e rua o te whārite ki te 30, arā, te tauraro pātahi he tino iti rawa te kitea o 3,6,5.
-10x+10=-5-6\left(x-1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -10 ki te x-1.
-10x+10=-5-6x+6
Whakamahia te āhuatanga tohatoha hei whakarea te -6 ki te x-1.
-10x+10=1-6x
Tāpirihia te -5 ki te 6, ka 1.
-10x+10+6x=1
Me tāpiri te 6x ki ngā taha e rua.
-4x+10=1
Pahekotia te -10x me 6x, ka -4x.
-4x=1-10
Tangohia te 10 mai i ngā taha e rua.
-4x=-9
Tangohia te 10 i te 1, ka -9.
x=\frac{-9}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{9}{4}
Ka taea te hautanga \frac{-9}{-4} te whakamāmā ki te \frac{9}{4} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
