/4 y + 1 1/2 + 2-1 3/4 y -12

=1/5x-3

/2 h + 1 from 3/4 h +4

1: =−3.225y+−92

2: x=40
 
3: =14fhm3or+12h+4

1) 1/4y + 1 1/2 + 2 - 1 3/4y - 12
= 1/4y + 3/2 + 2 - 7/4y - 12
= 1/4y - 7/4y + 3/2 - 10
= 6y / 4 - 17/20

In short, Your Answer would be: 3y/2 - 17/20

2) 5 = x/5 - 3
x/5 = 5 + 3
x = 8 * 5
x = 40

In short, Your Answer would be 40

3) [ If you are asking about subtraction ]
 3h/4 + 4 - (h/2 + 1 )
 3h/4 - h/2 + 4 - 1
  3h - 2h /4 + 3
= h/4 + 3

In short, Your Answer would be: 1/4 h + 3

Hope this helps!
