Kua tāruatia ki te papatopenga
3x+3=4-4x
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 1-x.
3x+3+4x=4
Me tāpiri te 4x ki ngā taha e rua.
7x+3=4
Pahekotia te 3x me 4x, ka 7x.
7x=4-3
Tangohia te 3 mai i ngā taha e rua.
7x=1
Tangohia te 3 i te 4, ka 1.
x=\frac{1}{7}
Whakawehea ngā taha e rua ki te 7.
