Question

(257 + 379) - a = 121
b + (267 + 348) = 916
c-(365 + 96) = 329
d-(848-426) = 379​

Answer 1

( 257 + 379 ) - a = 121

636 - a = 121

-a = 121 - 636

-a = -515

a = 515

b + ( 267 + 348 ) = 916

b + 615 = 916

b = 916 - 615

b = 301

c - ( 365 + 96 ) = 329

c - 461 = 329

c = 329 + 461

c = 790

d - ( 848 - 426 ) = 379

d - 422 = 379

d = 379 + 422

d = 801
