Answer:
p + q = 1
Step-by-step explanation:
(37p + 53q =69) + (53p + 37q = 21)
=> 37p + 53q - 69 + 53p + 37q - 21 = 0
(For solving this equation take all variables on LHS side and change the sign of RHS side)
=> 37p + 53p + 53q + 37q - 69 - 21 = 0
=> 90p + 90q - 90 = 0
=> 90p + 90q = 90
Hence, p + q = 1 (By cancelling 90 on both side)
