Solve the system of linear equations. what is the value of y? 9x−6y=15 6x+21y=60

y = 5

y = 2.2

Step-by-step explanation:

For the first one:

9x = 9 x1 = 9

9 - 6 = 3

3y = 15

15 ÷ 3 = 5

y = 5

For the second one:

6x = 6 x 1 = 6

6 + 21 = 27

27y = 60

60 ÷ 27 ~ 2.2

y = 2.2

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.
