Answer 1

4,5-у=8,7/5,8

4,5-у=1,5

у=4,5-1,5

у=3

Answer 2

4,5-у=8,7:5,8=1,5

4,5-1,5=3

Ответ: у=3

Answer 3

To solve the expression (4,5-у)*5,8=8,7, we need to find the value of "у." The expression is written in a format that might not be familiar, so let's clarify the notation first. It seems like the decimal separator used is a comma (","), which is common in some countries.

Let's rewrite the expression using a dot (".") as the decimal separator, which is more widely used internationally:

(4.5 - у) * 5.8 = 8.7

Now, the equation becomes clearer. We want to find the value of "у" that satisfies the equation.

Step 1: Distribute the multiplication on the left side of the equation:

4.5 * 5.8 - 5.8 * у = 8.7

Step 2: Perform the multiplication:

26.1 - 5.8 * у = 8.7

Step 3: Now, isolate "у" on one side of the equation. To do this, let's move the constant term (8.7) to the other side:

-5.8 * у = 8.7 - 26.1

Step 4: Simplify the right side:

-5.8 * у = -17.4

Step 5: To solve for "у," divide both sides by -5.8:

у = -17.4 / -5.8

Step 6: Calculate the result:

у = 3

So, the value of "у" that satisfies the equation is 3.
