Question

What are the solutions to the following system of equations?
y = x2 + 3x − 7
3x − y = −2

anonymous · Answer

are you familiar with substitution method?

anonymous · Answer

no not really

anonymous · Answer

well it is not that hard 
what you need to do is 
substitute the u with the second expression and solve for x 
so 
it would be 
$$3x -(x^2+3x-7) = 7 $$
see what i did?
i got the y expression and plugged it in to the second y

anonymous · Answer

yes what would you do next?

anonymous · Answer

simplify it by combining the like terms
so 
the 3x cancels out 
$$-x^2+3x-3x+7-7= 0 $$so  $$-x^2+0+0 = 0 $$$$-x^2 = 0 $$$$x^2 = 0 $$ $$x = 0 $$to find y, plug the x value in to one of the equation and solve for y

so would it be (3, 11) and (−3, −7) @helpme1.2
