X + y = -36
x * y = 160
x = -36 - y
(-36-y) * y = 160
-36y - y^2 = 160
y^2 + 36y + 160 = 0
y = -5.19 and x = -30.8
or
y = -30.8 and x = -5.19
You can write them in this form too

Answer:
c)
Step-by-step explanation:
create a system of equations:
d + m = 104
2d + 3m = 243
now use substitution method based on 'd = 104 - m'
2(104 - m) + 3m = 243
208 - 2m + 3m = 243
208 + m = 243
m = 35
