×+2supra3-7supra4=x+5​

[tex] \frac{x + 2}{3} - \frac{7}{4} = x + 5 \\ \frac{4x + 8}{12} - \frac{21}{12} = x + 5 \\ \frac{4x + 8 - 21}{12 } = x + 5 \\ 4x - 13 = 12 \times (x + 5) \\ 4x - 13 = 12x + 60 \\ 4x - 13 - 60 = 12x \\ 4x - 73 = 12x \\ - 73 = 8x \\ x = - 73 \div 8 \\ x = - 9.125[/tex]

x+ 2/3-7/4=x+5

x+ 8/15-21/15 ( am amplificat)=x+5

x+ 13/15=x+5

x/1+ 13/15=x+5

16x/15+ 13/15=x+5

28x/15=5x/1

28x * 1 = 15 * 5x

28x= 75x
