Question

Afla numerele necunoscut:a)x+2874=6322 1079+x=3456 b)7802-x=4576 x-5216=1075 c)8005-x=5008 7174-x=978

Answer 1

a)
X + 2874 = 6322
X = 6322 - 2874
X = 3448

1079 + X = 3456
X = 3456 - 1079
X = 2377

b)
7802 - X = 4576
X = 7802 - 4576
X = 3226

X - 5216 = 1075
X = 1075 + 5216
X = 6291

c)
8005 - X = 5008
X = 8005 - 5008
X = 2997

7174 - X = 978
X = 7174 - 978
X = 6196.
