Kua tāruatia ki te papatopenga
4\left(x+4\right)-2\left(3-4x\right)=5-x
Me whakarea ngā taha e rua o te whārite ki te 8, arā, te tauraro pātahi he tino iti rawa te kitea o 2,4,8.
4x+16-2\left(3-4x\right)=5-x
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x+4.
4x+16-6+8x=5-x
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 3-4x.
4x+10+8x=5-x
Tangohia te 6 i te 16, ka 10.
12x+10=5-x
Pahekotia te 4x me 8x, ka 12x.
12x+10+x=5
Me tāpiri te x ki ngā taha e rua.
13x+10=5
Pahekotia te 12x me x, ka 13x.
13x=5-10
Tangohia te 10 mai i ngā taha e rua.
13x=-5
Tangohia te 10 i te 5, ka -5.
x=\frac{-5}{13}
Whakawehea ngā taha e rua ki te 13.
x=-\frac{5}{13}
Ka taea te hautanga \frac{-5}{13} te tuhi anō ko -\frac{5}{13} mā te tango i te tohu tōraro.
