Bonsoir,
2 x a + 5x c=
2a+5c
ax d + 5 x 8 =
ad+40
38 (3 + 2 * c) =
38( 3+2c)
= 114+76c
3 * Z - 0× b =
=3z
3 * 7 - d x b =
=21 - db
a (3 * 9 + b + n) =
=27 +b+n
0x u + 1 x m=
= m
ax 6x n + 3 * p =
=6an +3p
9 m 5+ k*j* 8 =
= 9m*5 (??) + 8kj
= 45m (?) +8kj
Réponse:
2a + 5c
ad + 40
114 + 76 + 38c = 190 + 38c

21 - db
a (27 + b + n) = 27a + ab + an
m
6an + 3p
45m + 8kj
