Answer:
(x+22) + x = 88
Step-by-step explanation:
if x is how much your friend collected, then how much you collected would be x + 22 because you collected 22 more then her. and if you add both of those together to get how much you collected together (the total) you get 88. so x (your friends sea shells) plus x+22 (your sea shells) is 88. tell me if you also need help solving the actual equation
you have x+22 + x = 88
you combine like terms, in this case the Xs
and you get 2x + 22 = 88
then you subtract 22 to both sides because you want to get x alone
and you get 2x = 88 - 22
which is 2x = 66
then you divide by 2 on both sides
and you get x = 66/2
and you get x = 33
