Question

(7 + 8x) + (13 – x) + (2x – 9) = 29​

Answer 1

Ответ:

$7 + 8x + 13 - x + 2x - 9 = 29 \\ 11 + 9x = 29 \\ 9x = 18 \\ x = 2$

Answer 2

Ответ:

x=2

Пошаговое объяснение:

т.к между скобками знак "+", значит мы можем просто убрать скобки:

7+8x+13-x+2x-9=29

9x=18

x=2

Answer 3

To solve the equation (7 + 8x) + (13 - x) + (2x - 9) = 29, follow these steps:

Step 1: Combine like terms on the left side of the equation: 7 + 8x + 13 - x + 2x - 9 = 29

Step 2: Simplify the expression by adding or subtracting the coefficients of the x terms and the constants: (8x - x + 2x) + (7 + 13 - 9) = 29

Step 3: Further simplify the equation: 9x + 11 = 29

Step 4: Isolate the variable x by subtracting 11 from both sides of the equation: 9x = 29 - 11

Step 5: Simplify the right side: 9x = 18

Step 6: Finally, solve for x by dividing both sides by 9: x = 18 / 9 x = 2

So, the solution to the equation is x = 2.
