Kua tāruatia ki te papatopenga
\left(3\times 2+1\right)x=-21
Whakareatia ngā taha e rua o te whārite ki te 2.
\left(6+1\right)x=-21
Whakareatia te 3 ki te 2, ka 6.
7x=-21
Tāpirihia te 6 ki te 1, ka 7.
x=\frac{-21}{7}
Whakawehea ngā taha e rua ki te 7.
x=-3
Whakawehea te -21 ki te 7, kia riro ko -3.
