2х+18

                     =12

Х-3

 

To solve this equation, we need to isolate the variable (X) on one side of the equation.

First, we can simplify both sides by combining like terms:

2X + 18 = 12X - 3

Next, we can move all the X terms to one side and all the constant terms to the other side:

2X - 12X = -3 - 18

Simplifying further:

-10X = -21

Finally, we can solve for X by dividing both sides by -10:

X = 2.1

Therefore, the solution to the equation 2X + 18 = 12X - 3 is X = 2.1.
