10x-5=3\left(x+10\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 2x-1.
10x-5=3x+30
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+10.
10x-5-3x=30
Tangohia te 3x mai i ngā taha e rua.
7x-5=30
Pahekotia te 10x me -3x, ka 7x.
7x=30+5
Me tāpiri te 5 ki ngā taha e rua.
7x=35
Tāpirihia te 30 ki te 5, ka 35.
x=\frac{35}{7}
Whakawehea ngā taha e rua ki te 7.
x=5
Whakawehea te 35 ki te 7, kia riro ko 5.
