Résoudre les équations:

a) x + 3 = 18

x = 18 - 3

x = 15


b) 5 + y = -20

y = -20 - 5

y = -25


c) a - 10 = 16

a = 16 + 10

a = 26


d) -5 + t = -24

t = -24 + 5

t = -19

Résoudre ces équations

a.)
x + 3 = 18
x = 18 - 3
x =15

b.)
5 + y = -20
y = -20 - 5
y = -25

c.)
a - 10 = 16
a = 16 + 10
a = 26

d.)
-5 + t = -24
t = -24 + 5
t = - 19
