Объяснение:

8x-1=9*(10-x)+198

8x - 1 = 90 - 9x + 198

8x - 1 = 288 - 9x

8x + 9x = 288 + 1

17x = 289

x = 289 : 17

x = 17

Answer 3

To solve the equation 8x - 1 = 9 * (10 - x) + 198, follow these steps:

Step 1: Distribute the 9 on the right side of the equation.

9 * (10 - x) + 198 = 90 - 9x + 198 = 288 - 9x

Now, the equation becomes:

8x - 1 = 288 - 9x

Step 2: Combine the x terms on one side of the equation. Add 9x to both sides.

8x + 9x - 1 = 288 - 9x + 9x

Simplify:

17x - 1 = 288

Step 3: Isolate the x term. Add 1 to both sides.

17x - 1 + 1 = 288 + 1

Simplify:

17x = 289

Step 4: Solve for x. Divide both sides by 17.

x = 289 / 17

x ≈ 17

The solution to the equation is approximately x = 17.
