The variable for Maggie will be M and 2x-3 be her younger brothers age (<u>Twice her age). </u>We then would turn this into <u>an algebraic problem</u>. (m+2x -3=24).
3x-3=24, we would add 3 to both sides (-3 and 24). 24 + 3 equals 27, we now have to divide -3x and 27 on both sides, which equals <u>9. (x=9)</u>

Answer with Step-by-step explanation:
Let F be a field .Suppose  and
 and 
We have to prove that a has unique multiplicative inverse.
Suppose a has two inverses b and c
Then,  where 1 =Multiplicative identity
 where 1 =Multiplicative identity

 (cancel a on both sides)
 (cancel a on both sides)
Hence, a has unique multiplicative inverse.
