x - 3 = 1 b) 2x - 3 = 17 c) - 2x - 2 = - 5
x = 1 + 3 2x = 17 + 3 - 2x = - 5 + 2
x = 4 2x = 20 - 2x = - 3 .(- 1)
x = 20/2 2x = 3
x = 10 x = 3/2
=============================================
d) 3x - 1 = 0 e) 5 - 2x = - 17 f) 1 - x = - 1
3x = 1 - 2x = - 17 - 5 - x = - 1 - 1
x =1/3 - 2x = - 22 . ( - 1) - x = - 2 .( - 1 )
2x = 22 x = 2
x = 22/2
x = 11
x = 1 + 3 2x = 17 + 3 - 2x = - 5 + 2
x = 4 2x = 20 - 2x = - 3 .(- 1)
x = 20/2 2x = 3
x = 10 x = 3/2
