Answer:
x= -12
Step-by-step explanation:
Assuming this is a direct variation
y = kx
When y = -16 x =4 we can find k
-16 = k*4
Divide each side by 4
-16/4 = 4k/4
-4 =k
So
y = -4k
Y = 48
48 = -4x
Divide each side by -4
48/-4 = -4x/-4
-12 =x
Answer:
father is 41
Step-by-step explanation:
J = johns age
f = fathers age
j+f = 58
j = f-24
Substitute the second equation into the first
f-24 +f = 58
2f -24= 58
Add 24 to each side
2f = 58+24
2f =82
f = 82/2
f = 41
