Question

Sistema Linear:

a+2b+3c=260
2a+b+c=150
4a+3b+c=290

Answer 1

a=260-2b-3c 104+3b+c=150
52+b+c=150
b+c=98.(-1)
3b+c=46.(1)
2b=-52 b=-26
c=46-78
c=32
a=260-2.(-26)-3.(32)
a=260+52-96
a=260-44
a=216

Answer 2

Resposta:216

Explicação passo a passo:

a=260-2b-3c 104+3b+c=150

52+b+c=150

b+c=98.(-1)

3b+c=46.(1)

2b=-52 b=-26

c=46-78

c=32

a=260-2.(-26)-3.(32)

a=260+52-96

a=260-44

a=216
