Question

Sarah has a bag of green and yellow marbles. The number of yellow marbles is 2 less than double the number of green marbles. If you let g be the variable for the green marbles and y be the variable for the yellow marbles, which equation represents the relationship between yellow and green marbles? Sarah has a total of 16 marbles. Which equation represents the total number of marbles she has?Sarah has a bag of green and yellow marbles.

Answer 1

Explanation:

If you let g be the variable for the green marbles and y be the variable for the yellow marbles, which equation represents the relationship between yellow and green marbles?

✔ y = 2g - 2

Sarah has a total of 16 marbles. Which equation represents the total number of marbles she has?

✔ y + g = 16

Answer 2

`y = 2g - 2`

`y + g = 16`

Explanation:

Given

Let g represent the green marbles

Let y represent the y marbles

Required

Determine the relationship between both marbles

The question says that y is 2 less than twice of g

This implies that:
`y = 2g - 2`

The question further states that, Sarah has a total of 16 marbles;

This implies that
`y + g = 16`

So, the system of equation that defines the relationship between y and g are:

y = 2g - 2

y + g = 16
