Answer:
Step-by-step 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:
The question further states that, Sarah has a total of 16 marbles;
This implies that
So, the system of equation that defines the relationship between y and g are:
y = 2g - 2
y + g = 16
