Answer:
(-19, 6).
Step-by-step explanation:
3x + 11y = 9
-2x - 5y = 8
2(3x + 11y = 9)
3(-2x - 5y = 8)
6x + 22y = 18
-6x - 15y = 24
6x - 6x + 22y - 15y = 18 + 24
7y = 42
y = 6
3x + 11 * 6 = 9
3x + 66 = 9
3x = -57
x = -19
Check your work!
-19(-2) - 5(6) = 38 - 30 = 8
-19(3) + 11 * 6 = -57 + 66 = 9
Since everything works out, the solution to the system of equations is (-19, 6).
Hope this helps!

Simplify both sides of the equation
Subtract 2 from both sides
Divide both sides by 5
OR
Answer:6/36
Step-by-step explanation:
Rearrange to standard form:-
x^2 - 10x + y^2 = 11
(x - 5)^2 - 25 + y^2 = 11
(x - 5)^2 + y^2 = 36
Center of circle = (5, 0) and radius = sqrt36 = 6
