7x-35+2=-8x+12
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te x-5.
7x-33=-8x+12
Tāpirihia te -35 ki te 2, ka -33.
7x-33+8x=12
Me tāpiri te 8x ki ngā taha e rua.
15x-33=12
Pahekotia te 7x me 8x, ka 15x.
15x=12+33
Me tāpiri te 33 ki ngā taha e rua.
15x=45
Tāpirihia te 12 ki te 33, ka 45.
x=\frac{45}{15}
Whakawehea ngā taha e rua ki te 15.
x=3
Whakawehea te 45 ki te 15, kia riro ko 3.
