Need help with the subtracting and adding, steps included please!
ella [17]
I'm going to assume that you mean questions 1-5, so here we go:

1: w+4=16
You know that you need to find what w is equal to, so you need to get it on its own. To do that, you have to get rid of the four, so subtract 4 from each side.
w+4-4= 16-4
w=12

2. x+7= -12
This one is a little trickier, because the 12 is a negative. You still need to get x on its own, so subtract 7 from each side.
x+7-7= -12-7
-12-7= -19

so: x= -19

5. -2= y-9
This one is like the others, except it is subtracting instead of adding. If it helps, we will switch the problem around to make it easier to work with:
y-9= -2
First, you have to get y on its own, so to get rid of the 9, you have to add 9 to each side.
y-9+9= -2+9
Now we have:
y= 7


If you still need help with the rest of the questions, let me know and I'll talk you through the rest of them. Hope I can be of assistance;)
