Answer 2

Answer:

-1.99266667 or -1.99

Step-by-step explanation:

let the number subtracted be x

then 15-x:23-x= 7:15

=→ 15-x/23-x= 7/15

=→ 15-x = 7/15(23-x)

=→ 15-x = 10.73-7/15x

=→15-x×15x/-7= 10.73

=→ 15-15x/-7= 10.73

=→ -15x/-7= 10.73-15

=→ -15x/-7= -4.27

=→ x= -4.27×-7/-15

=→ x= 29.89/-15

=→ x= -1.99266667 or

-1.99266667 or -1.99
