Question

[(7+0,004x)/ 0,9]/24,7-12,3=77,7  

Answer 1

(7+0,004x)/(0,9*24,7)=77,7+12,3

7+0,004x=90*0,9*24,7

7+0,004x=2000,7

0,004x=1993,7

x=498425

Answer 2

To solve the equation:

[(7+0.004x)/0.9]/24.7 - 12.3 = 77.7

First, let's simplify the left-hand side of the equation by performing the division inside the brackets:

(7+0.004x)/(0.9*24.7) - 12.3 = 77.7

Now, let's multiply both sides of the equation by the denominator of the fraction on the left-hand side to eliminate the fraction:

7 + 0.004x - 0.924.7(77.7+12.3) = 0

Simplifying the right-hand side of the equation, we get:

7 + 0.004x - 182.16 = 0

Now, let's isolate the variable x by adding 182.16 to both sides of the equation:

0.004x = 175.16

Finally, we solve for x by dividing both sides by 0.004:

x = 43,790

Therefore, the solution to the equation is x = 43,790.
