6x+3-5\left(x-3\right)=23
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x+1.
6x+3-5x+15=23
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te x-3.
x+3+15=23
Pahekotia te 6x me -5x, ka x.
x+18=23
Tāpirihia te 3 ki te 15, ka 18.
x=23-18
Tangohia te 18 mai i ngā taha e rua.
x=5
Tangohia te 18 i te 23, ka 5.
