Answer 1

Ответ:

1,1

Объяснение:

21x-10x+14=24

11x=24-14

x=11/10=1,1

Answer 2

To solve the equation 21x - 5(2x - 7) = 24, we can follow these steps:

Step 1: Distribute the -5 to the terms inside the parentheses: 21x - 10x + 35 = 24

Step 2: Combine like terms: 11x + 35 = 24

Step 3: Move the constant term to the other side of the equation by subtracting 35 from both sides: 11x = 24 - 35 11x = -11

Step 4: Solve for x by dividing both sides of the equation by 11: x = -11/11 x = -1

Therefore, the solution to the equation 21x - 5(2x - 7) = 24 is x = -1.

I hope this helps! Let me know if you have any further questions.
