Kua tāruatia ki te papatopenga
7x+4+3x=-5
Me tāpiri te 3x ki ngā taha e rua.
10x+4=-5
Pahekotia te 7x me 3x, ka 10x.
10x=-5-4
Tangohia te 4 mai i ngā taha e rua.
10x=-9
Tangohia te 4 i te -5, ka -9.
x=\frac{-9}{10}
Whakawehea ngā taha e rua ki te 10.
x=-\frac{9}{10}
Ka taea te hautanga \frac{-9}{10} te tuhi anō ko -\frac{9}{10} mā te tango i te tohu tōraro.
