=> x+12 = 16
3
=>x+12= 16×3
=>x+12=48
=>x=48-12
=>x=36
required no=36
2. let me no. be x
5times of x=5x
ACCORDING TO THE QUESTION-
5x-19=41
=>5x=41+19
=>5x=60
=>x=60/5
=>x=12
3. let the no be x
1/4 of x=x/4
1/7 of x=x/7
ACCORDING TO THE
x/4-x/7=3
=>7x-4x=3
28
=>3x=3×28
=>3x=84
=>x=84/3
=>x=28
required no.=28
5. let the no. be= x
