Answer:
Resulting equation will be 5x²=36.
Step-by-step explanation:
The given equations are 5y = 10x-----(1)
and x²+y²=36------(2)
Now we substitute the value of y from equation (1) into equation (2).
5y = 10x ⇒ y = 2x
Then equation (2) will be x²+(2x)²=36
x²+4x²=36 ⇒ 5x² = 36
So the equation after substitution of the value of y from equation 1 will be 5x² = 36.

yes, no, no, yes, yes
Step-by-step explanation:
Answer: y=6, x=2
Step-by-step explanation:
Substitute x=12-y/3
Isolate y, then you get 6 is y
x=12-3/3
x=2
