Start by placing the second equation in for Y so you have
2x+2(5+x)=10
Then distribute the 2
2x+10+2x=10
Then combine like terms
4x+10=10
Then subtract the 10 over
4x=0
Then divide the 4 and because 0 divided by 4 is 0
x=0
Then plug it back into one, Ill choose the second
y=5+0
Then add 5+0 and you get y=5
Your solution is (0,5)
Hope I Helped! :) <3
