Kua tāruatia ki te papatopenga
8\left(4x-3\right)=5\left(2x-7\right)
Me whakarea ngā taha e rua o te whārite ki te 40, arā, te tauraro pātahi he tino iti rawa te kitea o 5,8.
32x-24=5\left(2x-7\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te 4x-3.
32x-24=10x-35
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 2x-7.
32x-24-10x=-35
Tangohia te 10x mai i ngā taha e rua.
22x-24=-35
Pahekotia te 32x me -10x, ka 22x.
22x=-35+24
Me tāpiri te 24 ki ngā taha e rua.
22x=-11
Tāpirihia te -35 ki te 24, ka -11.
x=\frac{-11}{22}
Whakawehea ngā taha e rua ki te 22.
x=-\frac{1}{2}
Whakahekea te hautanga \frac{-11}{22} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 11.
