Question

a + b = 300
b = cx9
c=d + 13
d=e: 6
e : 6 = 19​

Answer 1

e : 6 = 19

e = 19 × 6

e = 114

d = 114 : 6

d = 19

c = 19 + 13

c = 32

b = 32 × 9

b = 288

a + b = 300

a + 288 = 300

a = 300 - 288

a = 12

Answer 2

Răspuns:

e = 19 * 6 => e = 114

d = e : 6 => d = 114 : 6 => 19

c = d + 13 => c = 19 + 13 = 32

b = c * 9 => b = 32 * 9 = 288

a + b = 300 => a = 300 - 288 = 12
