Question

the question is A+B= 76 A-B =38 A÷B=.....??????

Answer 1

A+B= 76
A-B= 38
2A = 114. (on adding above equation)
A = 57
B =19
A/B = 57/19 = 3

Answer 2

A+B=76......1
A-B =38......2

2A =114
A=114/2
A=57

substitute A value in eq .1
57+B= 76
B=76 - 57
B=19

therefore A=57,B=57
then A÷B = 57÷19
=3
