Tohaina
Kua tāruatia ki te papatopenga
7x-14=5\left(x+3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te x-2.
7x-14=5x+15
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+3.
7x-14-5x=15
Tangohia te 5x mai i ngā taha e rua.
2x-14=15
Pahekotia te 7x me -5x, ka 2x.
2x=15+14
Me tāpiri te 14 ki ngā taha e rua.
2x=29
Tāpirihia te 15 ki te 14, ka 29.
x=\frac{29}{2}
Whakawehea ngā taha e rua ki te 2.
