@jhonyy9 how do you add an attachment?
here below the Attach file - window - push it and using this you can attach file easy - hope this will help you
3x+3y=27 x- 3y= -11 (8,1) (3,6) (6,3) (4,5)
its 4,5for the top 3*4 = 12 3*5 = 15 and 15 + 12 =27
2. Solve the system using elemination 4x-7y=3 x-7y= -15 (-12/5, 10/7) (-1,2) (6,3) (1, 1/7)
Sorry it takes forever to type it I'm having a difficult time adding an attachment
@mcgrath1010 we dont give the answers just help - how you have got this result ? make calculi for more easy understanding - ok ?
Nelly - do you understand first exercise how you need solve it ?
how you try it to solve - idea ?
when you need using elimination method what mean this ?
You need to divide right?
3x+3y=27 x- 3y= -11 ------------ this is an easy case because than you see the terms of y assumed +3y and - 3y will result zero yes ?
Nelly - try assuming these equation term by term - ok ?
Yes I see
than now just you need continue the calculi - what will get ?
I got b
are you here again ?
so not is right b. but please write the calculi here - how you calculi - ok :?
What is calculi?
how you solve this exercise ?
step by step
There's too much lag on my end but thanks for the help I'll have to watch
why ? this is very easy
3x+3y=27 x- 3y= -11 ------------ assum term by term 4x 0 = 16 x = 16/4 x=4 this mean that the last choise is right ,yes ?
second system please solve it you
There's a lot of lag
Nelly i like help you now and be secure that you understand how you can solve sytem same these using elimination method - ok ?
you dont like try it for i can checking your work now ?
ok. good luck bye
