Question

34+(46+х)=102. (c-35)+44=76. 70-( d+62)=5

Answer 1

$34 + (46 + x) = 102 \\ 46 + x = 102 - 34 \\ 46 + x = 68 \\ x = 68 - 46 \\ x = 22 \\ (c - 35) + 44 = 76 \\ c - 35 = 76 - 44 \\ c - 35 = 32 \\ c = 32 + 35 \\ c = 67 \\ 70 - (d + 62) = 5 \\ d + 62 = 70 - 5 \\ d + 62 = 65 \\ d = 65 - 62 \\ d = 3$
