First, find a common denominator.
2 and 1/3 = 2 and 3/9.
4 and 2/9 - 2 and 3/9 = 1 and 8/9. Hope it helps!
In order to solve by elimination, let's multiply the first equation by -2. This way, when we add the equations, the variable y will be canceled out:

Now, adding the equations, we have:

Now, calculating the value of y, we have:

Therefore the solution is (3, 0).
Hey!~
The chances that it will not rain "tomorrow" is 80%
Hope this helps and have a great day!
