Question

7⋅(2+x)−5x=3x−65. РЕШИТе пжлст

Answer 1

Ответ:

7(2+x)-5x=3x-65

14+7x-5x=3x-65

7x-3x-5x=-65-14

-x=-51

x=51

Answer 2

To solve the equation 7⋅(2+x)−5x=3x−65, follow these steps:

Step 1: Distribute the 7 on the left side of the equation: 7⋅2 + 7⋅x - 5x = 3x - 65

Step 2: Simplify the equation: 14 + 7x - 5x = 3x - 65

Step 3: Combine like terms on the left side of the equation: 14 + 2x = 3x - 65

Step 4: Move all the x terms to one side of the equation and the constant terms to the other side. Let's get all the x terms on the left side by subtracting 3x from both sides, and get all the constant terms on the right side by adding 65 to both sides: 2x - 3x = -65 - 14

Step 5: Simplify the equation further: -x = -79

Step 6: To solve for x, multiply both sides by -1 to get x by itself: x = 79

So, the solution to the equation is x = 79.
