Question

Como resolver este ejercicio 3x+1=7/4

Answer 1

3x + 1 = 7/4

3x = 7/4 - 1

3x = 7/4 -4/4

3x = 3/4

x = (3/4) / 3

x = 3/12
x = 1/4

Comprobacion
3(1/4) + 1 = 7/4
3/4 + 4/4 = 7/4
7/4 = 7/4

Answer 2

Resolver.

3x + 1 = 7/4

3x = 7/4 - 1

3x = (7 - 4)/4

3x = 3/4
 
  x = 3/4 : 3
 
 x = 3/4 * 1/3
 
 x = 3/12
   
 x = 1/4
