Question

Ajutati-ma va rog si pe mine la ex 19 va rog.

Answer 1

a) 245 + x =888

x = 888 - 245

x = 643

y + 235 = 434

y = 434 - 235

y = 199

z - 369 = 128

z = 128 + 369

z = 497

b) 122+323 - a = 115

122 + 323 - 115 = a

a = 330

122 + 100 = 124 + b

222 - 124 = b

b = 98

c - 222 = 321 + 103

c = 646

c) a + 7 < 11

a < 11 -7

a < 4

b + 28 < 32

b < 32 - 28

b < 4

c - 8 < 4

c < 4 + 8

c < 12

d - 36 < 5

d < 5 +36

d < 41
