Question

2a+2b=152. a-b=38. find the value of a÷b

Answer 1

Answer:

a/b=3

Step-by-step explanation

2a+2b=152............(1)

a-b=38

a =b+38..................(2)

substituting (2) in (1) , we get

2(b+38)+2b=152

2b+76+2b=152

4b =152-76

4b =76

b=76/4

»b=19

now, substituting b=19 in (2), we get

a=b+38

a=19+38

»a=57

now, a/b=57/19

a/b=3

Answer 2

Answer:

a-b=38

a=38+b.......1

from 1

2 (38+b)+2b=152

76+2b+2b=152

4b=152-76

4b=76

b=76/4

b=19

putting the value of b in equation 1

a-b=38

a-19=38

a=38+19

a=57

a÷b=》57/19=》3 is the answer
