2x+45x=

To solve the equation 2x + 45x = 0, we can combine the like terms on the left side of the equation:

2x + 45x = (2 + 45)x = 47x

Now, the equation becomes: 47x = 0

To solve for x, we divide both sides of the equation by 47:

47x/47 = 0/47 x = 0

Therefore, the solution to the equation 2x + 45x = 0 is x = 0.
