Addition andnsubtraction in integers

35+60-75 should be it

[hollow wharf]

hold on
does that "giving a check" make tina lose $35?

yes

so let x be the balance

and deposited means to add $75 to her account right?

so let x be the balance (like i said lol)

x - 35 is what you get after she issued that check

and x - 35 - 60 is what tina is left with after the withdrawal

yep

so

finally, x - 35 - 60 + 75 is the last step

and x - (x - 35 - 60 + 75) = 20

so the change is $20

yea 35 should be negative

so thats why you subtract 35

so x - (x - 20) = x - x + 20 = 20

two negatives become positive

it was loss

no problem

im glad to hear that
