Question

7 ∙ (х – 35) + 15 = 50

Answer 1

7•(x-35)+15=50

раскрываем скобку

7х-245+15=50

переносим известное в правую часть уравнения, при этом меняя знак на противоположный

7х=245-15+50

7х=280

х=280:7

х=40

Ответ: х=40

Answer 2

7 ∙ (х – 35) + 15 = 50

7 * х - 245 + 15= 50

7 * х - 230 = 50

7 * х = 230 + 50

7 * х = 280

Х = 280 : 7

Х = 40

Answer 3

To solve the equation 7 ∙ (x – 35) + 15 = 50, follow these steps:

Step 1: Distribute the 7 on the left side of the equation:

7x - 7 * 35 + 15 = 50

Step 2: Simplify the equation:

7x - 245 + 15 = 50

Step 3: Combine like terms:

7x - 230 = 50

Step 4: Isolate the variable (x) term on one side by moving the constant term to the other side of the equation. You can do this by adding 230 to both sides:

7x = 50 + 230

Step 5: Simplify the right side of the equation:

7x = 280

Step 6: Finally, solve for x by dividing both sides by 7:

x = 280 / 7

x = 40

So, the solution to the equation is x = 40.
