Step-by-step explanation:
We need to solve the system of equations by substitutions.
The system of equations given are:
Let:
Putting value of y from eq(2) into eq(1)
So, value of x=5
Now putting value of x in eq 1 to find value of y:
So, value of y is 10.5
Solving the system of equations we get x=5 and y=10.5

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
