It should go like this:

(4z + 3) (3z - 4) / (3z - 4) (z + 2)

Then you just cancel out (3z -4) and (3z -4), and the final simplified form of this polynomial is:

(4z +3) / (z + 2)

Maggie's brother is 9 years younger than three times her age. The sum of their ages is 43. How old is Maggie?
bekas [8.4K]

Answer:

Maggie's age is 13 years

Step-by-step explanation:

Let

x ------> Maggie's brother age

y ------> Maggie's age

we know that

x+y=43 ------ > equation A

x=3y-9 ------> equation B

substitute equation B in equation A and solve for y

(3y-9)+y=43

4y=43+9

4y=52

y=13

therefore

Maggie's age is 13 years
