" 2.5 times a number 'n' " = 2.5n

" 2.5n  is subtracted from 6.1 " . . . . that's     6.1 - 2.5n

" the result is  -11.4 " . . . . .  so       6.1 - 2.5n = -11.4

Add  11.4  to each side :          17.5 - 2.5n = 0

Add  2.5n  to each side:            17.5 = 2.5n

Divide each side by  2.5 :            7 = n
