SOLUTION: Use the substitution method to find all solutions of the system equations. 4. x^2 + y^2 = 25 y = 2x 6. x^2 + y = 9 x- y + 3 = 0 8. x^2

SOLUTION: Use the substitution method to find all solutions of the system equations. 4. x^2 + y^2 = 25 y = 2x 6. x^2 + y = 9 x- y + 3 = 0 8. x^2 - y = 1 2x^2 +

Question 329127: Use the substitution method to find all solutions of the system equations.
4. x^2 + y^2 = 25
y = 2x
6. x^2 + y = 9
x- y + 3 = 0
8. x^2 - y = 1
2x^2 + 3y = 17
