Answer:
The solution to this system is (-2,1)
Step-by-step explanation:
The given system of equations is;
...eqn1
and
....eqn2
We make y the subject of the second equation to get:
...eqn3
We put eqn3 into eqn1 to get;
We expand to get:
Simplify both sides to get:
Put x=-2 into eqn3
The solution to this system is therefore (-2,1)

Answer:
Is this a trick question, because I see two pairs of "1 1" in there with spaces instead of a "+", so are they supposed to be "11"s or are there 3 separate expressions, or did someone accidentally two plusses?
But yeah, anyway. Assuming it's one expression with two 11s, by cold, hard, mathematical law of operations, it's 30.
You'd only get something else if you're not following mathematical procedures, like when doing certain types of logic programming.
