Question

(145 — (25 + х) : 3) ×2 = 30.​

Answer 1

(145-(25+x):3)*2=30

Ответ : x=365

Answer 2

To solve for the value of the variable "x" in the equation:

(145 - (25 + x) / 3) * 2 = 30

Follow these steps:

Step 1: Simplify the expression within the parentheses: (25 + x) / 3 = (25/3) + (x/3)

Step 2: Subtract the expression within the parentheses from 145: 145 - (25/3) - (x/3) = (435/3) - (25/3) - (x/3) = (410/3) - (x/3)

Step 3: Multiply the result by 2: 2 * ((410/3) - (x/3)) = (820/3) - (2x/3)

Now you have the equation:

(820/3) - (2x/3) = 30

Step 4: Add (2x/3) to both sides to isolate the term with "x": (820/3) - (2x/3) + (2x/3) = 30 + (2x/3) (820/3) = 30 + (2x/3)

Step 5: Subtract 30 from both sides: (820/3) - 30 = (2x/3) (820 - 90) / 3 = (2x/3) 730 / 3 = (2x/3)

Step 6: Solve for x: 2x/3 = 730/3 2x = 730 x = 730 / 2 x = 365

So, the solution to the equation is x = 365.
