For the first equation, let's plug in x = 1:
5(1) + 5 = 5(1) + 4
5 + 5 = 5 + 4
10 = 9
Since the equation is false, this particular x value does not satisfy the equation, indicating that there is only one solution.
Now, for the second equation, let's plug in x = 2:
3(2) + 18 = 5(2) + 4
6 + 18 = 10 + 4
24 = 14
Again, the equation is false when x = 2, proving that there is only one solution.

When x is 1, the first equation is like 5 times 1 plus 5 equals 5 times 1 plus 4. Then we do the math: 5 plus 5 is 10 and 5 plus 4 is 9. Since 10 is not the same as 9, there's only one answer.
Now let's look at the second equation with x as 2. It goes like 3 times 2 plus 18 equals 5 times 2 plus 4. Doing the math, we get 6 plus 18 equals 10 plus 4, which is 24 equals 14. That's also not the same, showing that there's only one solution.
