Answer 2

Ответ:

1+0,5 x + 15,8= 12,8 - 0,7x

0,5 x+0,7x=12,8-15,8

0,13x=-3

X= -3 : 0 ,13

X= - 1 ( целая) 3/4 ( дробь)

Answer 3

To solve the equation 1 - (0.5x - 15.8) = 12.8 - 0.7x, you can follow these steps:

1. First, distribute the negative sign inside the parentheses on the left side of the equation:

1 - 0.5x + 15.8 = 12.8 - 0.7x

2. Next, move like terms to the same side of the equation. You can do this by adding 0.7x to both sides and subtracting 15.8 from both sides:

1 - 0.5x + 0.7x - 15.8 = 12.8 - 0.7x + 0.7x

3. Simplify the equation by combining like terms:

(1 + 0.7x - 0.5x) - 15.8 = 12.8

0.2x - 15.8 = 12.8

4. Now, add 15.8 to both sides of the equation to isolate the variable term:

0.2x - 15.8 + 15.8 = 12.8 + 15.8

0.2x = 28.6

5. Finally, divide both sides by 0.2 to solve for x:

(0.2x)/0.2 = 28.6/0.2

x = 143

So, the solution to the equation is x = 143.
