(2X + 3) +( 3X + 4) + (5X + 5) = 12 - 7x

Let's simplify the left side of the equation first:

(2X + 3) + (3X + 4) + (5X + 5) = 12 - 7X

First, combine like terms on the left side: 2X + 3 + 3X + 4 + 5X + 5 = 12 - 7X

Now, add the X terms and the constant terms separately: (2X + 3X + 5X) + (3 + 4 + 5) = 12 - 7X

Add the X terms together: 10X + (3 + 4 + 5) = 12 - 7X

Combine the constant terms: 10X + 12 = 12 - 7X

Now, let's move all the terms to the left side to get the equation in standard form: 10X + 7X + 12 = 12 - 12X

Combine the X terms: 17X + 12 = 12 - 12X

Now, let's move all the X terms to the right side: 17X + 12X = 12 - 12

Combine the X terms: 29X = 0

Now, divide both sides by 29 to solve for X: X = 0/29

Therefore, the solution is X = 0.
