Question

Hello! I need help with a math problem, this is the question:

Answer 1

Answer:

CN Tower = 550 m and church tower = 160 m

Step-by-step explanation:

The first equation x + y = 710 is correct

but the second one is

x - y = 390    

Note x = height of the CN tower and y = height of the church.

x + y = 710

x - y = 390

If we add the 2  above equations we eliminate y so

2x = 1100

x = 550 m

and y = 710 - 550 =  160 m
