Kua tāruatia ki te papatopenga
3x+15=2\left(3-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+5.
3x+15=6-2x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3-x.
3x+15+2x=6
Me tāpiri te 2x ki ngā taha e rua.
5x+15=6
Pahekotia te 3x me 2x, ka 5x.
5x=6-15
Tangohia te 15 mai i ngā taha e rua.
5x=-9
Tangohia te 15 i te 6, ka -9.
x=\frac{-9}{5}
Whakawehea ngā taha e rua ki te 5.
x=-\frac{9}{5}
Ka taea te hautanga \frac{-9}{5} te tuhi anō ko -\frac{9}{5} mā te tango i te tohu tōraro.
