To solve for x, we need to get the variable terms on one side of the equation and the constant terms on the other side.
Subtract 2x from both sides:
-3 = 3x + 9
Subtract 9 from both sides:
-12 = 3x
Divide by 3 to solve for x:
x = -4
Therefore, the solution to the equation 2x - 3 = 5x + 9 is x = -4.
