Bonjour,
a. -2 + x = 5
x = 5+2 = 7
b. x + 9 = 16
x= 16-9 = 7
c. 6x = 15
x= 15/6 = 5/2
d. -5x = 24
x= -24/5
e. 4x + 3x = 49
7x = 49
x= 49/7 = 7
f. -2x + 7x = 36
5x = 36
x= 36/5
a. -2 + x = 5
x = 5+2
x = 7
b. x + 9 = 16
x = 16 - 9
x = 7
c. 6x = 15
x = 15/6
x = 5/2
d. -5x = 24
x = -24/5
e. 4x + 3x = 49
7x = 49
x = 49/7
x = 7
f. -2x + 7x = 36
5x = 36
x = 36/5
