<h3>What is a system of equations?</h3>A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Wale's age.
- Variable y: Ajay's age.
Wale was twice as old as Ajay 10 years back, hence:

Answer:
1/2
Step-by-step explanation:
There are exactly 6 shaded regions; for every shaded region, there is also an unshaded region -- making this value 6 as well.
There are 12 possible outcomes, and 6 events
To determine probability, we divide the number of events by the number of possible outcomes, like this:
.50 = 50% or 1/2 chance.
