merci de resoudre l'equation 24/7×+1/14=3/28

24/7x + 1/4 = 3/28

On multiplie tout par 28 pour enlever les quotients.

672/7x + 28/4 = 84/28
96x + 7 = 3
96x = 3 - 7
96x = - 4
x = - 4/96
x = - 1/24

24/7x + 1/14 = 3/28
24/7x + 1/14 - 3/28 = 0
24/7x + 2/28 - 3/28 = 0
24/7x  - 1/28 = 0
(24*4) /(7x * 4)  - (x /28x) = 0
(24*4) /(7x * 4)  - (x /28x) = 0
96 /28x  - (x /28x) = 0
(96  - x) /28x = 0
(96  - x)  = 0 * 28x
(96  - x)  = 0
 -x = -96
x = 96
