Question

2198=2•(50•b + 50•11+b•11)

Answer 1

Răspuns:

2198=2•(50•b + 50•11+b•11)

2198=2·(50b+550+11b)

2198=2(61b+550)

2198=122b+1100

2198-1100=122b

1098=122b

b=1098:122=>b=9

Answer 2

$2198=2*(50*b + 50*11+b*11)$

$2*(50b+550+11b) = 2198$

$2*(61b+550)=2198$

$122b+1100=2198$

$122b=2198-1100$

$122b=1098=> b=\frac{1098}{122} => b=9$
