Since one equation has a negative y and the other has a positive y, I'm going to use those since they cancel each other out. Before that, the two y's need to be equal to each other.
x+2y=6
x-y=3
Multiply the bottom equation by two so then you have:
x+2y=6
2x-2y=6
The y's now cancel out:
x=6
2x=6
Add them together
3x=12
Divide
x=4.
To find y, plug x into either equation (*don't have to do both, but I will)
(4)+2y=6
(4)-y=3
Subtract four
2y=2
-y=-1
Divide each
2y/2 = 2/2
y=1
-y/-1 = -1/-1
y=1
The answer is:
x=4
y=1
I hope that helps!

Answer:
The answer is 30.6 Units.
Step-by-step explanation:
~10+~5+~10+~5=~30.6
I will assume that function f(x) = 6(0.25)^x
The domain of this function is all the real numbers.
Reflection accross the y-axis => the argument is multiplied by - 1. and g(x) is 6(0.25)^(-x).
The graph of the original function flips around the y-axis, but the domain keeps being all the real numbers.
Answer: all real numbers
