Question

a + b + c + d = 116.223
a= 61.002
b= 61.002 : 2
c= 3 x d + 120
b, c, d = ?
​

Answer 1

Răspuns:

b=30501

c=18570

d=6150

Explicație pas cu pas:

b=61002:2= 30501

a+b+c+d=116223 <=> c+d=116223-61002-30501

c+d=24720

c=3xd+120 => 4d+120=24720

4d=24600

d=24600/4

d=6150

c=3x6150+120

c= 18570

V: 61002+30501+18570+6150=116223

Answer 2

61.002 + 61.002 : 2 + c + d=116.223
30.501 + c + d=116.223 - 61.002
30.501 + c + d=55.221
c + d=55.221 - 30.501
c + d=24.720
c= 3 x d +120
3d + 120 + d=24.720
4d + 120=24.720
4d=24.720 - 120
4d=24.600
d=24.600:4
d=6.150
c= 3 x 6.150 +120
c= 18.450 +120
c= 18.570
b= 30.501
