We can simplify 2√5+3√5-√5 because they all have the same radical, √5. Now that we know this, we can imagine that there are no radicals, and that we are just adding numbers. This results in our expression being 2 + 3 - 1. This gives an answer of 4. Finally, we add the √5 to the 4 to get 4√5.

Answer:
x = 68/33
Explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 2/5x from both sides.
Step 3: Add 80 to both sides.
Step 4: Multiply both sides by 5/198.
Difference between x and y is 25
lets say x is bigger
x-y=25
smaller is 1/6 of larger
y=x/6
sub x/6 for y in other equation
x-(x/6)=25
times both sides by 6
6x-x=150
5x=150
divide both sides by 5
x=30
y=x/6
y=30/6
y=5
the smaller number is 5
