Kua tāruatia ki te papatopenga
-2x-3\left(x+9\right)=4x+3
Pahekotia te 7x me -9x, ka -2x.
-2x-3x-27=4x+3
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x+9.
-5x-27=4x+3
Pahekotia te -2x me -3x, ka -5x.
-5x-27-4x=3
Tangohia te 4x mai i ngā taha e rua.
-9x-27=3
Pahekotia te -5x me -4x, ka -9x.
-9x=3+27
Me tāpiri te 27 ki ngā taha e rua.
-9x=30
Tāpirihia te 3 ki te 27, ka 30.
x=\frac{30}{-9}
Whakawehea ngā taha e rua ki te -9.
x=-\frac{10}{3}
Whakahekea te hautanga \frac{30}{-9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
