Answer 1

a)

$\bf 1347 + x = 2012$

$\bf x = 2012 - 1347$

$\boxed{\bf x = 665}$

b)

$\bf 789-x=297$

$\bf 789=297+x$

$\bf 789-297=x$

$\boxed{\bf x=492}$

Answer 2

Explicație pas cu pas:

a)

1 347+x=2 012

x=2 012-1 347

x=665

v:1 347+665=2 012

b)

789-x=297

x=789-297

x=492

v:789-492=297
