24x=6 6+z=8









81x=9 7-x=20

Answer 1

Resolver.

24x = 6
 
    x = 6:2/24:2
 
    x = 3:3/12:3
 
    x = 1/4

.......................................................................

6 + z = 8

z = 8 - 6

z = 2

...............................................................................

81x = 9 
 
    x = 81/9
  
    x = 9

.................................................................................

7 - x = 20

x = 20 + 7

x = 27

Answer 2

24x=6
$x=\frac{6}{24} = \frac{1}{4}$

6+z=8
z=8-6
z=2

81x=9
x=$\frac{9}{81}= \frac{1}{9}$

7-x=20
7-20=x
-13=x
x=-13
