Answer:
-4/5
Step-by-step explanation:
3/5+(-7/5)
Since there are a + sign and a - sign next to each other, they cancel out to make a - sign.
3/5 - 7/5
Now, we can subtract.
3/5 - 7/5 = -4/5
Hope this helps! :)

<h3>
Answer:</h3>
- A) p = 5, one solution
- B) no solutions
- C) infinite solutions
<h3>
Step-by-step explanation:</h3>
A) Add 19-5p to each side of the equation:
... 10 = 2p
... 5 = p . . . . . divide by the coefficient of p
B) Subtract 5p from both sides of the equation:
... -9 = -19 . . . . . there is <em>no value of p</em> that will make this true. (No solution.)
C) Subtract 5p from both sides of the equation:
... -9 = -9 . . . . . this is true for <em>every value of p</em>. (Infinite solutions.)
