Solve the following system of equations for z and for y :
system of equations: value of z of y
y = 9 + 3z
y = 65 − 5z

Use the discriminant to describe the roots of each equation. then select the best description. 2m2 + 3 = m double root real and rational roots real and irrational roots non-real roots
