Question 738561: I am allowed to chose a method of choice...I am primarily confused by the way the equation is written. y + 2 = 0
5x - 2y= 9
Not sure how to use the substitution method when the "y" does not start with y=
I am also not sure how to use addition method when there is not an "x" in the first equation.
Thank you very much for your time and help in advance!!

y+2=0
-2 -2
Y=-2
SUBSTITUTE IN SECOND EQUATION
5x-2y=9
5x-2(-2)=9
5x+4=9
-4 -4
5x=5
/5
x=1
------------------
0x+1y=2...................(1)
5x-2y=9....................(2)
multiply eq.(1) by -2
we get
0+2y=-4
5x-2y=9
add up
5x=5
/5
x=1
y=2
