Question

(x+155-215)*2=1032+155

Answer 1

Решение:

(x + 155 - 215) × 2 = 1032 + 155;

2x + 155 × 2 - 215 × 2 = 1 187;

2x + 310 - 430 = 1 187;

2x = 1 187 - 310 + 430;

2x = 1 307;

x = 1 307 ÷ 2;

x = 653,5.

Ответ: 653,5.

Answer 2

Let's solve the equation step by step:

1. Start by simplifying the expressions on both sides of the equation:

   (x + 155 - 215) * 2 = 1032 + 155

2. Simplify inside the parentheses:

   (x - 60) * 2 = 1032 + 155

3. Distribute the 2 on the left side:

   2x - 120 = 1032 + 155

4. Now, let's isolate the variable x. First, add 120 to both sides of the equation:

   2x = 1032 + 155 + 120

5. Combine the numbers on the right side:

   2x = 1307 + 120

6. Add 1307 and 120:

   2x = 1427

7. Finally, divide both sides by 2 to solve for x:

   x = 1427 / 2

   x = 713.5

So, the solution to the equation is:

x = 713.5
