What is the question you are trying to ask?
Answer:
y = -49 x = 69
Step-by-step explanation:
make an equation
x+y=20 and x-y=118
then you can solve by elimination
x+y=20
x-y=118
=2x=138
x=69
69-y=118
-y=49
y=-49
Answer:
10.
Step-by-step explanation:
I am assuming that z is a whole number.
160z = x^2
z = x^2/ 160.
160 = 2*2*2*2*2*5
To make this a perfect square we multiply by 2 * 5
- this gives us 1600.
z = 1600/160 = 10.
