Answer 2

235-Х×9+342=397

235-Х×9=397-342

235-Х×9=55

Х×9=235-55

Х×9=180

Х=180÷9

Х=20

235-20×9+342=397

397=397

Answer 3

To solve the equation 235 - 9x + 342 = 397, follow these steps:

Step 1: Combine like terms on the left side of the equation. 235 + 342 = 577 577 - 9x = 397

Step 2: Isolate the variable term (9x) on one side by moving the constant term (397) to the other side. 577 - 397 = 180 9x = 180

Step 3: Solve for x by dividing both sides by the coefficient of x (which is 9). x = 180 / 9 x = 20

So, the solution to the equation is x = 20.
