Question

2. Calcule el valor de X
a. 4x + 10x = 28
b. X+2=9
c. 26x+x=27
d. 9 + x + 6x = 51
e. 10x + 11x + 9x= 90​

Answer 1

Explicación paso a paso:

calculamos el valor de x :

a/

4x +10x = 28

14x = 28

x= 2

b/

x+2 = 9

x= 9+2

x= 7

c/

26x+x = 27

27x = 27

x= 1

d/

9+ x + 6x = 51

9+7x = 51

7x = 51-9

7x = 42

x= 6

e/

10x + 11 x + 9 x = 90

30x = 90

x= 90/30

x= 3
