Question

Resolva o seguinte sistema linear, passo a passo

Answer 1

Resposta:

C=+1

d= -3/4

Explicação passo-a-passo:

2+2c+4d= 1

1 -2c-4d= 2. -8

8+4c+12d=3

2+2c+4d= 1

-8 +16c+32d= -16

8 +4c+12d =3

2 +2c+4d=1

-8+16c+32d=-16

0+20c+44d=-13

2 +2c+4d=1. *4

-8+16c+32d=-16

0+20c+44d=-13

8 +8c+16d=4.

-8+16c+32d=-16

0+20c+44d=-13

8 +8c+16d=4.

0 +24c+48d=-12

0+20c+44d=-13. -6/5

8 +8c+16d=4.

0 +24c+48d=-12

0-24c-52,8d=+78/5

8 +8c+16d=4.

0 +24c+48d=-12

0 + 0c-24/5d= +18/5

Se -24d=5*18/5 d=-3/4

24c-36=-12

24c=24

C=1
