Question

Află numărul x.
a. 214 + x = 5 003
823-X = 597
x - 198 = 5718
b. xx5 = 85
K:8 = 165
90:2 = 9
c. 12; x = 16 : 8
x x 10 = 80 : 2
x + x = 245 + x​

Answer 1

raspuns:

214+x=5003

x=5003-214

x=4789

823-x=597

x= 823-597

x=226

x-198=5718

x=198+5718

x=5916

b. raspuns:

x5=85

x=85:5

x=17

K:8=165

K=165×8

K= 1320
