2w + 4c = 67.90         Multiply this equation by - 2.5  (we are trying to get the 'w' to cancel out)

5w + 9c = 160.25

-5w -10c = -169.75     Now add the bottom two equations

- c = -9.50

c = = $9.50 Feb 5, 2021 #2 +11380 +1 2 wallets and 4 caps cost $$67.90\ \ and\ 5\ wallets\ and\ 9\ caps\ cost$$ 160.25$. what is the cost of 1 cap?

Hello Guest!

$$2w+4c=67.90\ |\ \times 5\\ \underline{5w+9c=160.25}\ |\ \times -2$$

$$\ 10w\ +\ 20c=\ 339.50\\ \underline{-10w-18c=-320.50}$$  |  add

$$2c=19$$

$$c=9.50$$

The cost of 1 cap is 9.50\$.
