Lian is deciding which of two gyms to join. each gym charges a monthly rate plus a one-time membership fee.
lian correctly wrote and solved a system of linear equations by substitution to compare the costs of the memberships. in her work, she substituted an expression for one variable and solved for the other. this resulted in the equation 75 = 75. what can lian conclude?
