Kua tāruatia ki te papatopenga
2x-3+5\left(4x-1\right)=5
Whakareatia ngā taha e rua o te whārite ki te 5.
2x-3+20x-5=5
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 4x-1.
22x-3-5=5
Pahekotia te 2x me 20x, ka 22x.
22x-8=5
Tangohia te 5 i te -3, ka -8.
22x=5+8
Me tāpiri te 8 ki ngā taha e rua.
22x=13
Tāpirihia te 5 ki te 8, ka 13.
x=\frac{13}{22}
Whakawehea ngā taha e rua ki te 22.
