Explanation

x/5 + 4 = x/4 -10

x/5 - x/4 = -10 -4

4x - 5x /20 = -14

4x - 5x = -14 x 20

- x = - 280

x = 280

Explanation

6 machines produce 270 bottles per minutes -> 1 machine produces (270/6) = 45 bottles per minute.

If each machine individually produces 45 bottles, then 10 machines will produce 10*45 = 450 bottles per minute.

In 4 minutes, the 10 machines will produce 450*4 = 1800 bottles in total.
