Question

HELP 1 MEDAL
What are the solutions to the following system of equations?
y = x2 + 3x - 7
3x - y = -2

Answer 1

replace the y in the second equation with "x2+3x-7" and that'll find you y. After that, substitute the answer into one of the equations and solve for x

Answer 2

apply same method here which i told you before

Answer 3

3x+2=y
now put it in eq(1)
3x+2=x^2 +3x -7
x^2 +3x -3x -7 -2 =0
x^2 -9 = 0
x^2 = 9
taking square root here on both sides
\[x=\pm3\]

now first put x= 3 and x =-3
y =3x +2

y = 3(3)+2 or y = 3(-3)+2
y= 9+2 or y = -9+2
y=11 or y =-7
Hence the solution set is that
={ ( 3,11 ) , ( -3,-7 )}

Answer 4

marrylin tthis is the solurtion of it

Answer 5

thank you so much!!!!
