C) -23x + 12 .. You're going to multiply the 4 to what's inside the parenthesis. So you'll get 12-24x+x Then just add the like terms which are the x's. 12-23x or -23x+12

2/3w - 1/4 = 2/3(w - 1/4)

Rufina [12.5K]

Answer:

No solution

Step-by-step solution:

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.
