Question

При каком значении переменной x значение выражения 2x−9 равно 4?

Answer 1

2x-9=4

2x=4+9

2x=13

x=13:2

x=6,5

Answer 2

2x=9+4
2x=13
X=13\2
X=6,5

Answer 3

To find the value of the variable x when the expression 2x - 9 is equal to 4, you can set up the equation and solve for x:

2x - 9 = 4

First, add 9 to both sides of the equation to isolate the term with x:

2x = 4 + 9 2x = 13

Now, to solve for x, divide both sides by 2:

x = 13 / 2 x = 6.5

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