Answer:
The solution to the system of equations be:

Step-by-step explanation:
Given the system of equations
4x-2y = 16
y = -5x+13
Solving the system of equations using the substitution method

Substitute y = -5x+13 in 4x-2y = 16



Now isolate x for 

Add 26 to both sides

Simplify

Divide both sides by 14

Simplify

For y = -5x+13
Substitute x = 3

Simplify

Therefore, the solution to the system of equations be:

1 blue jar = 21 marbles
1 blue jar = 3 red jars
Therefor
21 marbles= 3 red jars
