bonjour;
a) 5 x + 8 x - 3 x = 10 x
13 x - 3 x = 10 x
10 x = 10 x
b / p + 0.03 p = 1.03 p
1 .03 p = 1.03 p
c/ 5 ( 2 y - 3 ) + 11 = 10 y - 4
10 y - 15 + 11 = 10 y - 4
10 y = 4 = 10 y - 4
d/ 2 ( z + 1.5) - 0.1 z = 1 .9 z + 3
2 z + 3 - 0.1 z = 1.9 z + 3
1.9 z + 3 = 1.9 z + 3
e/ 4 ( 6t - 6 ) = - 24 ( 1 - t )
24 t - 24 = - 24 + 24 t
f / 2 ( n + 3) - 3 ( n - 5 ) = 21 - n
2 n + 6 - 3 n + 15 = 21 - n
- n + 21 = - n + 21
