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.

What is the answer for this

1). 2x-1=5 (cause x can really be anything) solve the equation to get x=3 or in this case, triangle = 3.

2). Using the info from above, we get the equation 3+x=1.
Solving this equation we get, x (square) =-2.

3). Using all the info from the above problems we get the equation: 3-2*-2=x
Solving that we see that x (star) equals 7.

In conclusion:

Triangle=3
Square=-2
Star=7
