Question

0,67:(19,2-0,4x)=0,1

Answer 1

0,67 : (19,2 - 0,4х) = 0,1
19,2 - 0,4х = 0,67 : 0,1
19,2 - 0,4х = 6,7
1 вариант:
-0,4х = 6,7 - 19,2
-0,4х = -12,5
х = -12,5 : -0,4
х = 31,25
2 вариант:
0,4х = 19,2 - 6,7
0,4х = 12,5
х = 12,5 : 0,4
х = 31,25

Answer 2

To solve the equation 0,67:(19,2-0,4x)=0,1, we can follow these steps:

1. Simplify the expression on the left-hand side of the equation by performing the division of 0.67 by the expression (19.2-0.4x):

   0.67/(19.2-0.4x) = 0.1

2. Multiply both sides of the equation by (19.2-0.4x):

   0.67 = 0.1(19.2-0.4x)

3. Distribute the multiplication on the right-hand side of the equation:

   0.67 = 1.92 - 0.04x

4. Subtract 1.92 from both sides of the equation:

   -1.25 = -0.04x

5. Divide both sides of the equation by -0.04:

   x = 31.25

Therefore, the solution to the equation 0,67:(19,2-0,4x)=0,1 is x = 31.25.
