Answer 3

To solve the equation 15 + 12y - 12y + 18 = 42, we can simplify the equation by combining like terms and then isolate the variable y.

Simplifying the equation:

Starting with the left side of the equation, we have: 15 + 12y - 12y + 18

Combining the like terms, the equation becomes: 33 + 0y + 18

Simplifying further, we have: 33 + 18 = 51

So the equation simplifies to: 51 = 42

Solving the equation:

Since the equation 51 = 42 is not true, it means that there is no solution to the equation. This means that there is no value of y that satisfies the equation.

In other words, the original equation 15 + 12y - 12y + 18 = 42 is inconsistent and has no solution.

I hope this helps! Let me know if you have any further questions.
