Question

69 - (y – 28) = 13; с прверкой​

Answer 1

69-(y - 28)=13

y-28=69 - 13

y - 28= 56

y = 56 + 28

y = 84

69 - (84 - 28) = 13

Answer 2

Ответ:

69-(у-28)=13

69-у+28=13

-у=13-28-69

у=-84

Answer 3

To solve the equation 69 - (y - 28) = 13, we can follow these steps:

Step 1: Simplify the equation by removing the parentheses: 69 - y + 28 = 13

Step 2: Combine like terms: 97 - y = 13

Step 3: Solve for y by isolating the variable. To do this, we'll subtract 97 from both sides of the equation:

• y = 13 - 97
• y = -84

Step 4: Multiply both sides of the equation by -1 to isolate y: y = 84

So the solution to the equation 69 - (y - 28) = 13 is y = 84.

Let's verify this solution by substituting it back into the original equation: 69 - (84 - 28) = 13

First, let's simplify the expression inside the parentheses: 69 - (56) = 13

Now, let's subtract 56 from 69: 13 = 13

The left-hand side is equal to the right-hand side, so the solution y = 84 is correct.
