2/3w - 1/4 = 2/3(w - 1/4)
Rufina [12.5K]

<u>Answer:</u>

No solution

<u>Step-by-step solution:</u>

We are given an expression:

\frac{2}{3} w-\frac{1}{4} =\frac{2}{3} (w-\frac{1}{4} )

We have only one variable w so we will make w the subject and solve for it.

\frac{2}{3} w-\frac{1}{4} =\frac{2}{3} (w-\frac{1}{4} )

Solving the brackets first to get:

\frac{2}{3} w -\frac{1}{4} =\frac{2}{3} -\frac{1}{6}

Taking LCM on both sides to get:

\frac{8w-3}{12} =\frac{4w-3}{6}

By cross multiplication:

6(8w-3)=12(4w-3)

48w-18 = 48w -36

48w - 49w -18 + 36 = 0

w gets cancelled so we are left with 18\neq 0

Therefore, w has no solution.
