5x-25-2\left(3x-4\right)=13-2x
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-5.
5x-25-6x+8=13-2x
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 3x-4.
-x-25+8=13-2x
Pahekotia te 5x me -6x, ka -x.
-x-17=13-2x
Tāpirihia te -25 ki te 8, ka -17.
-x-17+2x=13
Me tāpiri te 2x ki ngā taha e rua.
x-17=13
Pahekotia te -x me 2x, ka x.
x=13+17
Me tāpiri te 17 ki ngā taha e rua.
x=30
Tāpirihia te 13 ki te 17, ka 30.
