Given that x + y = 180, p + q = 180, and p = x. Show that y = q.
Which step would be used to prove the argument?
Responses
A x + p = 180x + p = 180
B x + y = p + qx + y = p + q
C y + q = 180y + q = 180
D 2x + 2y = 1802x + 2y = 180
1 answer
I would choose option B: x + y = p + q. This step combines the given equations x + y = 180 and p + q = 180.
