Answer 3

To solve the equation, combine like terms on the left side first:

3x - 2x + 8x = 18

To combine the x terms, add the coefficients of x:

(3 - 2 + 8)x = 18

Now, simplify the left side:

9x = 18

To isolate x, divide both sides of the equation by 9:

x = 18 / 9

Now, perform the division:

x = 2

So, the solution to the equation is x = 2.
