Hello it's me again. I really have a hard time
solving problems with equations.I'm lucky that you're there. Thank you so much.
Here's how I got that answer (????)
2x-13=77
2x=77+13
2x=90
x=90/2
x=45 (???)
Please follow Steve's direction. Check to see if Kiwi's age is 45. Does that make sense?
will check and post it once i'm done.thanks
hint: it's x + 2x-13 = 77
x+2x-13=77
3x-13=77
3x=77+13
3x=90
x=90/3
x=30 Kiwi's age
