Solve for ww, where ww is a real number and 2w15w10=0\sqrt{2w-1} - \sqrt{5w-10} = 0. If there is more than one solution, separate them with commas. If there is no solution, click on "No solution".

STEP 1

Assumptions
1. We are solving for a real number ww.
2. The equation to solve is 2w15w10=0\sqrt{2w - 1} - \sqrt{5w - 10} = 0.
3. We assume that ww must be such that the expressions under the square roots are non-negative, since we are dealing with real numbers.

STEP 2

Isolate one of the square roots on one side of the equation.
2w1=5w10\sqrt{2w - 1} = \sqrt{5w - 10}

STEP 3

Square both sides of the equation to eliminate the square roots. Remember that squaring both sides of an equation maintains equality.
(2w1)2=(5w10)2\left(\sqrt{2w - 1}\right)^2 = \left(\sqrt{5w - 10}\right)^2

STEP 4

Simplify both sides of the equation after squaring.
(2w1)=(5w10)(2w - 1) = (5w - 10)

STEP 5

Subtract 2w2w from both sides to start isolating ww.
1=3w10-1 = 3w - 10

STEP 6

Add 10 to both sides to further isolate ww.
9=3w9 = 3w

STEP 7

Divide both sides by 3 to solve for ww.
w=93w = \frac{9}{3}

STEP 8

Calculate the value of ww.
w=3w = 3

STEP 9

We must verify that our solution w=3w = 3 does not lead to taking the square root of a negative number in the original equation.
2(3)15(3)10=611510=55=0\sqrt{2(3) - 1} - \sqrt{5(3) - 10} = \sqrt{6 - 1} - \sqrt{15 - 10} = \sqrt{5} - \sqrt{5} = 0

STEP 10

Since the solution w=3w = 3 satisfies the original equation without resulting in the square root of a negative number, it is a valid solution.
The solution to the equation is: w=3 w = 3
