Hello from MrBillDoesMath!
Answer:
x = ( -9 + sqrt(33) ) /4
and
x = ( -9 - sqrt(33) ) /4
Discussion:
Using the quadratic formula with a = 2, b = 9 and c = 6 gives
x = ( -b +\- sqrt(b^2-4ac) )/2a
x = ( -9 +\- sqrt(9^2 - 4*2*6)) / (2*2) =>
x = ( -9 +\- sqrt (81- 48)) / 4 =>
x = ( -9 +\- sqrt(33) ) /4
Thank you,
MrB
Step-by-step explanation:
x+y=-2
x-y=-6
x=-2-y
(-2-y)-y=-6
-2-2y=-6
-2y=-4
y=2
x=-4
The answer is 0.9 if z is in the numerator and if it is in the denominator it is 1/9
