2\left(25x-125\right)=30\times 5
Me whakarea ngā taha e rua ki te 5.
50x-250=30\times 5
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 25x-125.
50x-250=150
Whakareatia te 30 ki te 5, ka 150.
50x=150+250
Me tāpiri te 250 ki ngā taha e rua.
50x=400
Tāpirihia te 150 ki te 250, ka 400.
x=\frac{400}{50}
Whakawehea ngā taha e rua ki te 50.
x=8
Whakawehea te 400 ki te 50, kia riro ko 8.
