Answer 2

Finding the Value of the Variable

To find the value of the variable when the sum of 6x and 18x is equal to 72, we can set up an equation and solve for x.

Let's denote the variable as x. The equation can be written as:

6x + 18x = 72

To solve this equation, we can combine the like terms on the left side:

24x = 72

Next, we can isolate x by dividing both sides of the equation by 24:

x = 72 / 24

Simplifying the right side gives us:

x = 3

Therefore, when the variable x is equal to 3, the sum of 6x and 18x is equal to 72.

Answer

The value of the variable x is 3 when the sum of 6x and 18x is equal to 72.
