Tohaina
Kua tāruatia ki te papatopenga
8x-3x+6=5\left(x+2\right)-4
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x-2.
5x+6=5\left(x+2\right)-4
Pahekotia te 8x me -3x, ka 5x.
5x+6=5x+10-4
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+2.
5x+6=5x+6
Tangohia te 4 i te 10, ka 6.
5x+6-5x=6
Tangohia te 5x mai i ngā taha e rua.
6=6
