Răspuns: [tex]\color{red}\Large \boxed{\bf x = 12}[/tex]
Explicație pas cu pas:
Buna!
[tex]\large \bf \dfrac{7x+6}{5}= \dfrac{5x+12}{4}\implies 4\cdot (7x+6)= 5\cdot (5x+12)\implies[/tex]
[tex]\large \bf 28x+24 =25x+60[/tex]
[tex]\large \bf 28x-25x+24 =60[/tex]
[tex]\large \bf 3x+24 =60[/tex]
[tex]\large \bf 3x=60 - 24[/tex]
[tex]\large \bf 3x=36~~~\bigg|:3[/tex]
[tex]\color{red}\Large \boxed{\bf x = 12}[/tex]
