72-8x=5\left(2-3x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te 9-x.
72-8x=10-15x
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 2-3x.
72-8x+15x=10
Me tāpiri te 15x ki ngā taha e rua.
72+7x=10
Pahekotia te -8x me 15x, ka 7x.
7x=10-72
Tangohia te 72 mai i ngā taha e rua.
7x=-62
Tangohia te 72 i te 10, ka -62.
x=\frac{-62}{7}
Whakawehea ngā taha e rua ki te 7.
x=-\frac{62}{7}
Ka taea te hautanga \frac{-62}{7} te tuhi anō ko -\frac{62}{7} mā te tango i te tohu tōraro.
