x-19-3x+6=3\left(4-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x-2.
-2x-19+6=3\left(4-x\right)
Pahekotia te x me -3x, ka -2x.
-2x-13=3\left(4-x\right)
Tāpirihia te -19 ki te 6, ka -13.
-2x-13=12-3x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 4-x.
-2x-13+3x=12
Me tāpiri te 3x ki ngā taha e rua.
x-13=12
Pahekotia te -2x me 3x, ka x.
x=12+13
Me tāpiri te 13 ki ngā taha e rua.
x=25
Tāpirihia te 12 ki te 13, ka 25.
