Substitute 2x as y:
3x + y = 5
3x + 2x = 5
5x = 5
x = 1
Now, substitue 1 as x into one of the two equations:
y = 2x
y = 2(1)
y = 2
Hope this helps!

The radical expression is D
The panthers won 40 games out of 60, by hypothesis.
Let x be the number of matches they will win out of 110 games, if they keep the same rate. We'll use the rule of three:
40 games ---> 60 games
x games ---> 110 games
x = (110*40) / 60
x = 4400/60
x ≈ 73.33
So the panthers, at this rate, will win 73 games out of 110.
Hope this helps! :)
