I need help solving -8 - p= -8 I understand that I need to find the value of p, but I dont understand what I need to do with it because it's a negative.
The answer to this is that p = 0. There are two ways you can go about finding this.
First, you can just do this by logic. If -8 minus something still equals -8, what could that something be? If you subtract something from a number and still get that same number, clearly you subtracted zero, right?
Second, you can actually do the math. First, add 8 to both sides to get rid of the -8 on the left side. That gives you
-p = 0
You then multiply both sides by -1 to get p to be positive. But 0 multiplied by anything is still 0 so
p = 0
To solve -8 -p = -8 go about it this way
-8 -p = -8
add -8 to both the sides
=> -8 -p +8 = -8 +8
=> -p =0
There you have it, -p = 0, which also means p = 0 as -1 multiplied by 0 is also 0.
ahhh thank you, I was so confused because my teachers been telling us that we can divide it by -1 or something, I did think about it for a second and felt a bit silly. But again, thank you!
The steps are the followings:
We'll have to add 8 both sides, in order to isolate -p to the left side:
-8 + 8 - p= -8 + 8
It is obvious that we'll get the result:
0 - p = 0
-p = 0
We'll have to multiply both sides by -1, in order to get a positive p:
p = -1*0
If we multiply any number by zero, the resul will be also 0, no matter if the number is positive or negative.
p = 0
