Kua tāruatia ki te papatopenga
8\left(2x-4\right)=5\left(4x+1\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.
16x-32=5\left(4x+1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te 2x-4.
16x-32=20x+5
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 4x+1.
16x-32-20x=5
Tangohia te 20x mai i ngā taha e rua.
-4x-32=5
Pahekotia te 16x me -20x, ka -4x.
-4x=5+32
Me tāpiri te 32 ki ngā taha e rua.
-4x=37
Tāpirihia te 5 ki te 32, ka 37.
x=\frac{37}{-4}
Whakawehea ngā taha e rua ki te -4.
x=-\frac{37}{4}
Ka taea te hautanga \frac{37}{-4} te tuhi anō ko -\frac{37}{4} mā te tango i te tohu tōraro.
