Question

3x/4-x/3=5

Quero cálculos

Answer 1

3x/4 - x/3 =5

a/b - c/d =(ad - bc)/bd

Então,

(3x.3 - 4.x)/4.3 = 5

(9x - 4x)/12 = 5

5x/12 = 5

5x = 5.12

x = (5.12)/5

x = 12

Answer 2

$\frac{3x}{4} - \frac{x}{3} = \frac{5}{1}$

$\frac{9x-4x}{12} = \frac{60}{12}$

$9x - 4x = 60$

$5x = 60$

$x = 15$
