Answer:

w = 13

Step-by-step explanation:

Using the method of cross- multiplying

• \frac{a}{b} = \frac{c}{d} ⇒ ad = bc, thus

42(w + 11) = 28(w + 23) ← distribute parenthesis on both sides

42w + 462 = 28w + 644 ( subtract 28w from both sides )

14w + 462 = 644 ( subtract 462 from both sides )

14w = 182 ( divide both sides by 14 )

w = 13
