Question

Cum aflu a si b dintr-un sistem de ecuatii:
12-2*a=0
b-1=0

Answer 1

$\left \{ {{12=2*a} \atop {b=1}} \right.$

$\left \{ {{a=12:2} \atop {b=1} }\right.$

$\left \{ {{a=6} \atop {b=1}} \right.$

Answer 2

Explicație pas cu pas:

12-2*a=0

2*a=g

12-g=0

g=12-0

g=12

2*a=12

a= 12:2

a=6

b-1=0

b=1+0

b=1
