Answer: (55,9) Explanation is below.
Step-by-step explanation:
What you want to do is try to mutliply one of your equations so that either y or x will be canceled out.
Here is the example:
Say you want to get rid of x, you can multiply the first equation: x-5y=10 by -2 to match the second equation: -2x+6y=-16.
Therefore, the first equation would become -2(x-5y=10)=> -2x+10y=-20
Then subtract the first equation from the second:
(-2x+6y= -16)
- (-2x+10y = -20)
-------------------------
=> 0x-4y= -36
Simplify and then you get y=9.
To find x, plug in y into one of the equations: x-5(9)=10 => x-45=10 => x=55
Sorry if I didn't explain it correctly.
