Binomial? I'm not sure what the options are but this is a binomial.
Let us assume that the age of Janet's sister is = x
Then the age of Janet = x + 5
Now we also know that their combined age is equal to 51 years. Then we can write the equation as
x + (x + 5) = 51
2x + 5 = 51
2x = 51 -5
2x = 46
x = 46/2
= 23
So the age of Janet = x + 5
= 23 + 5
= 28 years
So the age of Janet's sister is 23 and Janet's age is 28
Answer:
it make sense
Step-by-step explanation:
(X is another 2)
x-5=3
2x+1=5
we're gonna barrow 5 from the first question and get the answer in the second question
so..
5-5=0
hope it helps
