Answer:
Because the problem says - they are AT LEAST...
You would need to list the answers this way
GrandD is < or = to 5 GrandS is greater or = to 7
Step-by-step explanation:
These are so fun!
Let GrandD = X
Let GrandS = X + 2 (because he is two years older than GrandD)
Their age together is 12 years - so...
GrandD + GrandS = 12 OR...
x + x + 2 = 12
Now solve for x.
2x + 2 = 12
2x = 10 (because we subtract the ones on the left from the ones on the right)
x = 5 (because we divide both sides by 2)
This means that GrandD (x) is equal or greater than 5 years old
And GrandS (x + 2) = or greater than 7 years old
