The correct answer is S =7
You look at the sign behind the second term. Here are some examples...
2x + 8 - 4x
You are going to subtract 2x - 4x because there is a negative sign behind the 4x.
8y + 1 + y
You are going to add 8y + y because there is a positive sign behind the y.
4 + 2x - 5 + 7x
You are going to subtract 4 - 5 because there is a negative sign behind the 5.
You are going to add 2x + 7x because there is a positive sign behind the 7x.
