Question

1.) 15,7 : y + (3,071 – 2,5) = 0,572

Answer 1

$15.7 \div y + (3.071 - 2.5) = 0.572 \\ 15.7 + y \times 3.071 + y( - 2.5) = 0.572y \\ 15.7 + 0.571y = 0.572y \\ 15.7 + 0.571y - 0.572y = 0 \\ 15.7 - 0.001y = 0 \\ - 0.001y = - 15.7 \\ y = \frac{ - 15.7}{ - 0.001} \\ y = \frac{ - 15700}{ - 1} \\ y = 15700$

Answer 2

It looks like you have an equation here that involves some numbers and variables. Let's solve it step by step:

1. Start with the equation: 15.7 / y + (3.071 - 2.5) = 0.572

2. Simplify the expression inside the parentheses: 15.7 / y + 0.571 = 0.572

3. Next, subtract 0.571 from both sides of the equation to isolate the term with "y" on the left side: 15.7 / y = 0.572 - 0.571 15.7 / y = 0.001

4. To solve for "y," you can take the reciprocal of both sides of the equation to get "y" by itself: y = 15.7 / 0.001

5. Finally, divide 15.7 by 0.001 to find the value of "y": y = 15,700

So, the solution to the equation is: y = 15,700
