ok thanks for your help. so if im adding a positive and a negative do i take the sign of the higher number? or are the rules the same for adding and multiplying?

So in this case you will have to use the BODMOS rule(Brackets, Order, Divide, Multiply, Add, Subtract), so in our case there is multiply first to remove brackets, so:

2(3+7x)-15

1. Multiply: 6+14x-15

2.Then: 14x-9 = Answer.
