Solve the system of equations below. Please show your work algebraically, you do not need to graph (but you can check your answers graphically). y = x² - x – 20 y = 3x – 15

The transitive property of equality states that: o if a = b, then bra o if a = b, then ac = bc o if a = b and b= c, then a = if a = b and c= c, then a + b = b + c

A. 90 degrees b. 45 degrees c. 30 degrees d. 120 degrees
