9s + 7 = -11 9s = -18 s = -18/9 s = -2
x^2 + 3x + 7 = 6x + 18 x^2 - 3x - 11 = 0
s = negative 73 (-73)
How do you add 2x plus 3y equals 18 in 5x-y equals 11
2+14=16

9s + 7 = -11 9s = -18 s = -18/9 s = -2
3t+11 = 29 3t = 29-11 3t = 18 t = 6
x^2 + 3x + 7 = 6x + 18 x^2 - 3x - 11 = 0
xx+3x+7=6x+18 xx+3x+7-(6x+18)=6x+18-(6x+18) xx-3x-11=0 Factors of -11: 1,-11 -1,11 Doesn't factor evenly, use quadratic
s = -145
s = negative 73 (-73)
