Question

Rezolvati ecuatiile : ×+1 pe 2=3 pe 4 si 2x-1pe4 =1 pe 2

Answer 1

a) x+1 /2 = 3/4
    4(x+1)=6
    4x+4=6
    4x = 6-4
    4x=2
    x= 2/4
    x= 1/2

b) 2x-1 / 4 = 1/2
   2(2x-1)=4
   2x-1=2
  2x = 2+1
   2x=3
   x= 3/2

Answer 2

2x-1pe4 =1 pe 2

[tex]\it 2x -\dfrac{1}{4} = \dfrac{1}{2} \Leftrightarrow 2x = \dfrac{1}{2}+\dfrac{1}{4} \Leftrightarrow 2x = \dfrac{2}{4}+\dfrac{1}{4} \Leftrightarrow 2x = \dfrac{3}{4} \Big|_{\cdot \dfrac{1}{2}}\Leftrightarrow \\\;\\ \\\;\\ \Leftrightarrow x = \dfrac{3}{8}[/tex]
