a) 2(x +1) = 8
=> 2x + 2 = 8
=> 2x = 8 - 2
=> 2x = 6
=> x = 6/2
=> x = 3
b) 5(x - 1) = -15
=> 5x - 5 = -15
=> 5x = -15 + 5
=> 5x = -10
=> x = -10/5
=> x = -2
c) -5(x + 7)= -10
=> -5x - 35 = -10
=> -5x = -10 + 35
=> -5x = 25
=> x = -25/5
=> x = -5
d) 2(x - 1) = 6
=> 2x - 2 = 6
=> 2x = 6 +2
=> 2x = 8
=> x = 8/2
=> x = 4
e) 3(x - 2) = 2
=> 3x - 6 = 2
=> 3x = 2 + 6
=> 3x = 8
=> x = 8/3
f) 1( x - 2) = -3
=> x - 2 = -3
=> x = -3 +2
=> x = -1
