X=-11+y
10x-5y=-10
First: You would take your x and plug it in
You'll get: 10(-11+y)-5y=-10
Then: You'll distribute your 10
You'll get: -110+10y-5y=-10
Next: You'll combine like terms
You'll get: -110+5y=-10
Then: You'll add 110 on both sides of your equal sign so you can get your y alone
You'll get: 5y= 100
Next: You'll divide each side by 5 to where your y would be alone
You'll get: y=20 < That is your y
You'll now: Take what you got for your y and plug it into the easiet equation so you can solve for your x.
Equation being used: x=-11+y
Now: Plug in what you got for your y
You'll get: x=-11+20
Now: You'll add -11 and 20 together
You'll get: x=9
Your answer would be: (9, 20)
HOPE THIS HELPS! ^_^
