Question

При каком значении переменной x значение выражения 3x-15 равна 3?

Answer 1

3х-15=3
3х=15+3
3х=18
х=18/3
х=6

Answer 2

To find the value of the variable x when the expression 3x - 15 is equal to 3, you can set up an equation and solve for x:

3x - 15 = 3

Now, let's solve for x:

Add 15 to both sides of the equation to isolate the term with x:

3x = 3 + 15 3x = 18

Finally, divide both sides by 3 to solve for x:

x = 18 / 3 x = 6

So, when x is equal to 6, the value of the expression 3x - 15 is 3.
