2x-4-4x=3\left(5-x\right)+6
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-2.
-2x-4=3\left(5-x\right)+6
Pahekotia te 2x me -4x, ka -2x.
-2x-4=15-3x+6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 5-x.
-2x-4=21-3x
Tāpirihia te 15 ki te 6, ka 21.
-2x-4+3x=21
Me tāpiri te 3x ki ngā taha e rua.
x-4=21
Pahekotia te -2x me 3x, ka x.
x=21+4
Me tāpiri te 4 ki ngā taha e rua.
x=25
Tāpirihia te 21 ki te 4, ka 25.
