Answer:
C) (-1, -4) and (4, 6)
Step-by-step explanation:
Substitute Equation 1 into Equation 2 and solve for x:
Find two numbers that multiply to -4 and sum to -3: -4 and 1
Rewrite the middle term as the sum of these two numbers:
Factorize the first two terms and the last two terms separately:
Factor out the common term :
Substitute the found values of x into Equation 1 and solve for y:
Therefore, the solution to the system of equations is:
(-1, -4) and (4, 6)

i.e.
---- in 28 places
Andre's interpretation of the expression is incorrect as:
Also, Elena's expression is incorrect.
This is so, because
<em>Hence, both of them are incorrect and I agree with none of them</em>
