Answer 1

a) |x – 1| = 2x - 1

x – 1 = 2x – 1

2x + x = - 1 + 1

3x = 0

X = 0

b) 2x + |x – 1| = 2

2x + x - 1 = 2

3X = 2 + 1

3x = 3

X = 3/3  

X = 1

c) |3x + 7| = 5x + 13

3x + 7 = 5x + 13

3x – 5x = 13 – 7

- 2x = 6

x = - 6/2 = - 3

X = - 3

d) |3x + 2| = 5 - x

3x + 2 = 5 – x

3x + x = 5 – 2

4x = 3

X = 3/4

e) |5x + 4| = 2x + 1

5x + 4 = 2x + 1

5x – 2x = 1 – 4

3x = - 3

X = -3/3 = - 1

f) |- 6x + 1| = 4x – 7

- 6x + 1 = 4x – 7

8 = 10x

x = 8/10 = 4/5

g) X + |1 +2x| = - 2

X + 1 + 2x = - 2

3x = - 2 - 1

3x = - 3

X = -3/3 = - 1
