Kua tāruatia ki te papatopenga
15x-70=2\left(6x-0\times 5\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 3x-14.
15x-70=2\left(6x-0\right)
Whakareatia te 0 ki te 5, ka 0.
15x-70-2\left(6x-0\right)=0
Tangohia te 2\left(6x-0\right) mai i ngā taha e rua.
15x-70-2\times 6x=0
Whakaraupapatia anō ngā kīanga tau.
15x-70-12x=0
Whakareatia te -2 ki te 6, ka -12.
3x-70=0
Pahekotia te 15x me -12x, ka 3x.
3x=70
Me tāpiri te 70 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{70}{3}
Whakawehea ngā taha e rua ki te 3.
