Answer 1

0.988:(0.2x+0.8)=0.13
0.2x+0.8=0.13*0.988
0.2x+0.8=0.12844
0.2x=0.12844-0.8
0.2x=-0.67156
x=-0.67156:0.2
x=-3.3578

Answer 2

0,988:(0,2х+0,8)=0,13
Раскрываем скобки меняя знаки в внутри неё
0,988:(-0,2х)-0,8=13
4,94х-0,8=13
Переносимости все числа в нужные половины уровнения (при переносе за равно знак меняется.
4,94х=13+0,8
4,94х=13,08
х=13,08:(-4,94)
х=2 5/13

Answer 3

Solving the Equation 0.988 / (0.2x + 0.8) = 0.13

To solve the equation 0.988 / (0.2x + 0.8) = 0.13, we can follow these steps:

1. Isolate the Variable - First, we need to isolate the variable (x) by getting it on one side of the equation.

2. Simplify the Equation - Then, we simplify the equation to solve for the variable.

Step-by-Step Solution

1. Isolate the Variable - Multiply both sides of the equation by (0.2x + 0.8) to clear the fraction.

   0.988 = 0.13 * (0.2x + 0.8)
   

2. Simplify the Equation - Distribute 0.13 to both terms inside the parentheses.

   0.988 = 0.026x + 0.104
   

- Subtract 0.104 from both sides of the equation.

   0.884 = 0.026x
   

- Divide both sides by 0.026 to solve for x.

   x = 0.884 / 0.026
   

- Calculate the value of x.

Calculating the Value of x

Let's calculate the value of x:

x = 0.884 / 0.026
x ≈ 34

So, the solution to the equation 0.988 / (0.2x + 0.8) = 0.13 is approximately x ≈ 34.
