x=18:2

x=9

Answer 3

It seems like you're trying to solve a linear equation for the variable 'x.' Let's solve the equations step by step:

1. 4x + 5x = 18

Combine the like terms on the left side of the equation:

9x = 18

2. Now, you want to isolate 'x.' To do that, divide both sides of the equation by 9:

(9x) / 9 = 18 / 9

x = 2

So, the solution to the equation 4x + 5x = 18 is x = 2.

Now, let's look at the second equation:

9x = 18

To solve for 'x,' divide both sides of the equation by 9:

(9x) / 9 = 18 / 9

x = 2

So, the solution to the equation 9x = 18 is also x = 2.

In both cases, the value of 'x' is 2.
