Answer:
j ≥ -37
Step-by-step explanation:
j + 16 ≥ -21
move constant to the right hand side and change its sign
j ≥ -21 - 16
calculate the difference (subtract)
j ≥ -37
If x is the age of S
And y is the age of K
So we have x=y+3
And the second equation is x-3 + 2/3)y = 12
We have to solve the system
x-y=3
x+2/3y=15
we find x=10.2 and y=7.2
