In a parallelogram if AB = 3x + 2y and AB = 30 what is the value of x and y

1 answer:

5 0

We can put the two equations together with substitution, and we get

3x + 2y = 30

Now we have a single equation in two variables, so we don't have enough information to solve for both x and y.

Answer:

mary=10 jack=15

Step-by-step explanation:

After 4 years Mary (x+4), Jack's age (x+5) + 4.

sum of the ages after 4 years :(x+4) + (x+5) +4=33

Simplifying the equation:

2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age

10 + 5 = 15 which is Jack's age.
