By minusing 12 to both sides
d+12=2
-12=-12
d =-10
It's 3 (total number of have rabbits that's 43 - Have rabbits which is 40) 43-40= 3
Answer: a
Step-by-step explanation:
Let’s take fred age as x and Natalie’s age as y.
So,
A/Q
X + Y = 43. Let it be eqution 1
and
X + 4Y = 79. Let it be equation 2
Combining equation 1 and 2, we get
( X + Y) + 3Y = 79
43 + 3Y = 79
3Y = 36
Y = 12
Now, evaluating the value of Y in equation 1 we get,
X + 12 = 43
X = 31
Therefore, Fred is 31years old and Natalie is 12 years old.
