Kua tāruatia ki te papatopenga
9\times 5x=5\left(x-32\right)
Me whakarea ngā taha e rua o te whārite ki te 45, arā, te tauraro pātahi he tino iti rawa te kitea o 5,9.
45x=5\left(x-32\right)
Whakareatia te 9 ki te 5, ka 45.
45x=5x-160
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-32.
45x-5x=-160
Tangohia te 5x mai i ngā taha e rua.
40x=-160
Pahekotia te 45x me -5x, ka 40x.
x=\frac{-160}{40}
Whakawehea ngā taha e rua ki te 40.
x=-4
Whakawehea te -160 ki te 40, kia riro ko -4.
