Explanation:
Tina solved 15 hard puzzles.
We can use the system of equations:
X represents the easy puzzles
Y represents the hard puzzles
x+y=50
3x+6y=195 (I just divided everything by 10 to make things easier)
Then I multiplied the first equation by -3 to be able to cross out x and solve for y.
So now we have -3x-3y=-150.
Now we can add the equations together and we get:
-3x-3y=-150
3x+6y=195
+________
3y= 45
y=15.
That means that Tina solved 15 hard puzzles and 45 easy puzzles.
Hope this helps! (Plz thank)
