2х-9-9-1=0за ответ дам десять балов

Answer 1

2х-9-9-1=0
2х-19=0
2х=19
х=9,5

Answer 2

To solve the equation 2x - 9 - 9 - 1 = 0, follow these steps:

1. Combine the constants on the left-hand side: 2x - (9 + 9 + 1) = 0

2. Simplify the expression inside the parentheses: 2x - 19 = 0

3. Add 19 to both sides of the equation to isolate the variable term (2x) on one side: 2x = 19

4. Finally, divide both sides by 2 to find the value of x: x = 19/2 x = 9.5

So, the solution to the equation is x = 9.5.
