First, multiply the first equation by 3 to get:

Then, add the two equations together to get

We can follow that x=2. Plugging in x=2, we get that y=-4.
Therefore, the solution of (2,-4)
Answer:

A=43.0491 (4 .d.p.). B=53.7785 (4 .d.p.). C=83.1724 (4 .d.p.). Explanation: Labelling triangle in the conventional way i.e. side a opposite angle ...
Answer:
x²y²+xy²+3+xy+2y²
Step-by-step explanation:
(2x²y²+x²y+xy²+3)-(x²y²+x²y²+x²y-xy-2y²)
1. remove the parentheses (when there’s - in front of an expression in parentheses change the sign of each term of the expression)
2x²y² + x²y + xy² + 3-x²y² - x²y² - x²y + xy - 2y²
2. eliminate the opposites
2x²y² + xy² + 3 -x²y² + xy +2y²
3. collect like terms
x²y² + xy² + 3 + xy + 2y²
Answer:
y=4
Step-by-step explanation:
Because it is a horizontal line, there is no slope the only thing that is there is the y intercept
