Answer:
Step-by-step explanation:
A + b = 76
a = 76 - b
A - b = 38
Putting value of a
76 - b - b = 38
76 - 2b = 38
76 - 38 = 2b
38 = 2b
B = 38/2 = 19
A = 76 -b
= 76 - 19 = 57
A÷b = 57 ÷ 19 = 3
Hope it helps uh

Answer:
A ÷ B = 3
Step-by-step explanation:
A + B = 76 (i)
A - B = 38 (ii)
Adding equation (i) & (ii),
i.e,
2A = 114
=> A = 57 (iii)
Put value of A from eq (iii) in eq (i) & (ii),
i.e,
57 + B = 76
B = 76 - 57
=> B = 19 (iv)
Dividing eq (iii) by eq (iv),
i.e, A/B
57/19
=> 3
