-3(x+4)+15=6-4x
Tohaina
Kua tāruatia ki te papatopenga
-3x-12+15=6-4x
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x+4.
-3x+3=6-4x
Tāpirihia te -12 ki te 15, ka 3.
-3x+3+4x=6
Me tāpiri te 4x ki ngā taha e rua.
x+3=6
Pahekotia te -3x me 4x, ka x.
x=6-3
Tangohia te 3 mai i ngā taha e rua.
x=3
Tangohia te 3 i te 6, ka 3.
