Question

При каком значении переменной x значении выражении 2x-9 равно 4

Answer 1

$2x-9=4 \\ 2x=4+9 \\ 2x=13 \\ x = 6,5$

Answer 2

To find the value of the variable x when the expression 2x - 9 is equal to 4, we need to set up an equation and then solve for x.

The equation is: 2x - 9 = 4

Now, let's solve for x:

Add 9 to both sides of the equation to isolate the term with x: 2x = 4 + 9 2x = 13

Finally, divide both sides by 2 to solve for x: x = 13 / 2 x = 6.5

So, when x is equal to 6.5, the expression 2x - 9 is equal to 4.
