Question

1) 3 (5 - X)-3 (1 - 2X) = 42

2) (4 + 6) -2X = (X - 6) + 10 + 14

3) (X - 3) - (X + 2) + 2 ( X - 1) - 5 = 0

4) 3X - 2 (4X - 3)= 2 - 3 (X - 1

5) 3(X - 1) - (X - 3) + 5 (X - 2) = 18

6) 5(X - 3) -4 (X + 2) = 2 + 3 ( 1 - 2X) ​

Answer 1

1)

15-3x -3 +6x=42

3x+12=42

3x=42-12

3x=30

x=30/3

x=10

2)

$10 - 2x = x - 6 + 24 \\ - 2x - x = 18 - 10 \\ - 3x = 8 \\ x = - \frac{8}{3}$

3)

$x - 3 - x - 2 + 2x - 2 - 5 = 0 \\ x - x + 2x - 3 - 2 - 2 - 5 = 0 \\ 2x - 12 = 0 \\ 2x = 12 \\ x = \frac{12}{2} \\ x = 6$

4)

$3x - 8x + 12 = 2 - 3x + 3 \\ - 5x + 12 = - 3x + 3 +2 \\ - 5x + 3x = 5 - 12 \\ - 2x = - 7 \\ x = \frac{7}{2}$

5)

$3x - 3 - x + 3 + 5 x- 10 = 18 \\ 3x - x + 5x - 3 + 3 - 10 = 18 \\ 2x + 5x - 10 = 18 \\ 7x - 10 = 18 \\ 7x = 18 + 10 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4$

6)

$5x - 15 - 4x - 8 = 2 + 3 - 6x \\ 5x - 4x - 15 - 8 = 5 - 6x \\ x - 23 = 5 - 6x \\ x + 6x = 5 + 23 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4$
