-x-3=2\left(3.5-x\right)
Hei kimi i te tauaro o x+3, kimihia te tauaro o ia taurangi.
-x-3=7-2x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3.5-x.
-x-3+2x=7
Me tāpiri te 2x ki ngā taha e rua.
x-3=7
Pahekotia te -x me 2x, ka x.
x=7+3
Me tāpiri te 3 ki ngā taha e rua.
x=10
Tāpirihia te 7 ki te 3, ka 10.
