Answer 1

$\huge\bold\red{ᴀɴsᴡᴇʀ}$

$\tt \: \frac{ - 5}{7} = \frac{ - 20}{x} \: \: \: (by \: \: cross \: \: multiplication) \\ \\ \tt \: - 5 \times x = - 20 \times 7 \\ \\ \tt \: - 5x = - 140 \\ \\ \tt \: 5x = 140 \\ \\ \tt \: x = \frac{140}{5} \\ \\ \tt \: x = 28$

Answer 2

Answer:

If -5/7 = -20/x, then x is equal to​ 28.

Step-by-step explanation:

$\frac{-5}{7} = \frac{-20}{x}$

Cross multiplication

(-5)x = (-20) (7)

-5x = -140

x = 140/5

x = 28

So, if -5/7 = -20/x, then x is equal to​ 28.
