100-8+2x=69
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 4-x.
92+2x=69
Tangohia te 8 i te 100, ka 92.
2x=69-92
Tangohia te 92 mai i ngā taha e rua.
2x=-23
Tangohia te 92 i te 69, ka -23.
x=\frac{-23}{2}
Whakawehea ngā taha e rua ki te 2.
x=-\frac{23}{2}
Ka taea te hautanga \frac{-23}{2} te tuhi anō ko -\frac{23}{2} mā te tango i te tohu tōraro.
