Question

me ayudan porfa tengo q hallar x
en la 1 y la 2 ​

Answer 1

Respuesta:

X/4+X/3 = 7/2

7X/12 = 7/2

2(7X) = 7(12)

14X = 84

14X/14 = 84/14

X = 6

Comprobación :

(6)/4+(6)/3 = 7/2

6/4+2 = 7/2

14/4 = 7/2

(14÷2)/(4÷2) = 7/2

7/2 = 7/2

R// X vale 6

2) 7X/4-4X/3 = 5/6

5X/12 = 5/6

6(5X) = 5(12)

30X = 60

30X/3 = 60/3

10X = 20

10X/2 = 20/2

5X = 10

5X/5 = 10/5

X = 2

Verificación :

(7(2))/4-(4(2))/3 = 5/6

14/4-8/3 = 5/6 ; 14/4 = 7/2

7/2-8/3 = 5/6

(3(7)-2(8))/(2×3) = 5/6

(21-16)/6 = 5/6

5/6 = 5/6

R// X vale 2
