Kua tāruatia ki te papatopenga
2\left(-\frac{5\times 2+1}{2}\right)x=16\times 2+1
Whakareatia ngā taha e rua o te whārite ki te 2.
2\left(-\frac{10+1}{2}\right)x=16\times 2+1
Whakareatia te 5 ki te 2, ka 10.
2\left(-\frac{11}{2}\right)x=16\times 2+1
Tāpirihia te 10 ki te 1, ka 11.
-11x=16\times 2+1
Me whakakore te 2 me te 2.
-11x=32+1
Whakareatia te 16 ki te 2, ka 32.
-11x=33
Tāpirihia te 32 ki te 1, ka 33.
x=\frac{33}{-11}
Whakawehea ngā taha e rua ki te -11.
x=-3
Whakawehea te 33 ki te -11, kia riro ko -3.
