What is x minus 4.7 divided by 3 =-8

-6.73

Step-by-step explanation:

From the question x - 4.7/3.8 = -8; what is x?

Divide 4.7 by 3.8 by the calculator to give 1.27

Therefore, equation is written as:

x - 1.27 = -8

Add 1.27 to both sides of the equation

x - 1.27 + 1.27 = -8 + 1.27

x = -6.73

Converted to fraction is -673/100

-6 73/100

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
