What is the solution to the system of equations y=-2x-4 y=x+2

y = -2x - 4

y = x + 2

Because we have two values of y, we can set them equal to each-other.

-2x - 4 = x + 2

Add 2x to both sides.

-4 = 3x + 2

Subtract 2 from both sides.

-6 = 3x

Divide both sides by 3.

-2 = x

Because we have a value for x, we can plug it into either equation to solve for y.

y = -2(-2) - 4

y = 4 - 4

y = 0

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.
