3x+6x=18
Thanx!
9x = 18
Divide both sides of the equation by 9.
That will tell you the value of x.
x=2
To solve the equation 3x + 6x = 18, you need to combine like terms and then solve for x.
First, combine the x terms by adding the coefficients:
3x + 6x = 18
(3 + 6)x = 18
9x = 18
Next, isolate x by dividing both sides of the equation by 9:
(9x)/9 = 18/9
x = 2
So, the solution to the equation is x = 2.
