_
5
​

Answer 1

Answer:

a. x = 3

b. x = -3

c. x = -5

d. x = 4

e. x = 8/3

f. x = -1

hope it helps you

Answer 2

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
