Question

a•b=90 b=c•3 c=d:10,d-e=250,e:10=5

Answer 1

e=10x5

e=50

d-50=250

d=250+50

d=300

c=300:10

c=30

b=30x3

b=90

ax90=90

a=90:9

Answer 2

a • b = 90

b = c • 3

c = d ÷ 10

d - e = 250

e ÷ 10 = 5

____________________

a = ? b = ? c = ? d = ? e = ?

e ÷ 10 = 5

e = 10 • 5

e = 50

d - e = 250

d - 50 = 250

d = 250 + 50

d = 300

c = d ÷ 10

c = 300 ÷ 10

c = 30

b = c • 3

b = 30 • 3

b = 90

a • b = 90

a • 90 = 90

a = 90 ÷ 90

a = 1

Răspuns : 50, 300,30,90,1

Succes!
