Answer:
Step-by-step explanation:
Ok, well the first thing you need to do is make -4/13 have the same numerator as 9/26. Thankfully, 26 is a multiple of 13, so that step is easy:
-4/13 -> -8/26
Then you can add them together with ease.
9/26 + -8/26 = 1/26
Adding a negative number to anything is the same thing as subtracting.
p=-54
a - 8
b - 20
c - 40

x = 2
4x +4=12
-4. -4
4x.= 8
divide both saide by 4
x. = 2
