Question

14+(с-18)=31 решите уравнения

Answer 1

14 + (с - 18) = 31
(с - 18) = 31 - 14
с - 18 = 17
с = 18 + 17
с = 35
Ответ: 35.

Answer 2

To solve the equation 14 + (с - 18) = 31, follow these steps:

Step 1: Combine like terms on the left side of the equation. 14 + (с - 18) = 31 Combine the numbers 14 and -18: с - 4 = 31

Step 2: Isolate the variable с on one side of the equation. To do this, add 4 to both sides of the equation to get с alone on the left side: с - 4 + 4 = 31 + 4 с = 35

Step 3: Verify the solution. Now, substitute the value of с back into the original equation to check if it holds true: 14 + (35 - 18) = 31 14 + 17 = 31 31 = 31

The equation is valid, and the solution is с = 35.
