135x-315=38\left(x+2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te 9x-21.
135x-315=38x+76
Whakamahia te āhuatanga tohatoha hei whakarea te 38 ki te x+2.
135x-315-38x=76
Tangohia te 38x mai i ngā taha e rua.
97x-315=76
Pahekotia te 135x me -38x, ka 97x.
97x=76+315
Me tāpiri te 315 ki ngā taha e rua.
97x=391
Tāpirihia te 76 ki te 315, ka 391.
x=\frac{391}{97}
Whakawehea ngā taha e rua ki te 97.
