Question

1supra3x+2=2supra3
AJUTATIMA VA ROG

Answer 1

1/3x+2=2/3    ,, /'' inseamna SUPRA !
1/3x=2/3-2
1/3x=2/3-6/3 deoarece amplifici cu 3!
1/3x=-4/3
x=-4/3:1/3
x=-4/3*3/1 deoarece cand ai impartire a doua fractie se inverseaza
x=12/3 care se simplifica prin 3 
x=4/1=4

Answer 2

 $\frac{1}{3x}=\frac{2}{3}\;\;\Leftrightarrow\;\;6x=3\;deci:\;x=\frac{\;\;3^{(3}}{6}=\frac{1}{2}$
