Question

540 : (y + 12) - 9 = 18.​

Answer 1

Ответ:

540:(у+12)-9=18

540:(у+12)=18+9

540:(у+12)=27

у+12=540:27

у+12=20

у=20-12

у=8

540:(8+12)-9=18

540:20-9=18

27-9=18

18=18

Answer 2

To solve for the variable y in the equation 540 : (y + 12) - 9 = 18, you'll need to isolate y on one side of the equation. Here are the steps to do that:

1. Start with the original equation: 540 : (y + 12) - 9 = 18

2. First, add 9 to both sides of the equation to get rid of the -9 on the left side: 540 : (y + 12) = 18 + 9

3. Simplify both sides of the equation: 540 : (y + 12) = 27

4. Now, you want to get rid of the fraction on the left side by multiplying both sides of the equation by (y + 12): 540 = 27 * (y + 12)

5. Next, divide both sides by 27 to solve for (y + 12): (540) / 27 = (27 * (y + 12)) / 27

6. Simplify both sides: 20 = y + 12

7. Finally, isolate y by subtracting 12 from both sides of the equation: 20 - 12 = y

8. Simplify: 8 = y

So, the solution to the equation is y = 8.
