1/3 x− 1/8 y=3
7y+9x=−2
please solve the system
45 points for who does

Step-by-step explanation:

One method could be rewriting the second equation as x in terms of y and solving by replacing in the first equation.

Replace...

add on both sides.

Combine like terms

Now, to get rid of the fraction and isolate y, multiply by the reciprocal or the inverted fraction.

Simplify

Now replace the value of y in either equation to find x.

add 56

Divide by 9

To check whether these values are accurate, replace in either equation both values and you should have an equality. In this case I'll do it in both equations.

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.
