-32-72x=7\left(-2-11x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -8 ki te 4+9x.
-32-72x=-14-77x
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te -2-11x.
-32-72x+77x=-14
Me tāpiri te 77x ki ngā taha e rua.
-32+5x=-14
Pahekotia te -72x me 77x, ka 5x.
5x=-14+32
Me tāpiri te 32 ki ngā taha e rua.
5x=18
Tāpirihia te -14 ki te 32, ka 18.
x=\frac{18}{5}
Whakawehea ngā taha e rua ki te 5.
