Idont get this can someone plz explain it to me : '(

see below

Step-by-step explanation:

1)  2 1/2 + 3 = x,  x - 2 1/2 = 3, x - 3 = 2 1/2

2) 2  1/2 + 3 = x

   x = 5  1/2

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
