Answer 1

a)

$2x - 2 = \frac{ - 4x + 14}{3} \\ 6x - 6 = - 4x + 14 \\ 6x + 4x = 14 + 6$

$10x = 20 \\ x = \frac{20}{10} = 2 \\ x = 2$

b)

$\frac{6x + 4}{4} = \frac{3x + 9}{6} \\ 6(6x + 4) = 4(3x + 9) \\ 36x + 24 = 12x + 36 \\ 36x - 12x = 36 - 24 \\ 24x = 12 \\ x = \frac{12}{24} = \frac{1}{2}$

C)

$\frac{8x + 3}{12} = 5 \\ 8x + 3 = 60 \\ 8x = 60 - 3 \\ 8x = 57 \\ x = \frac{57}{8}$

d)

$\frac{24x - 30}{5} = \frac{ - 18x + 40 - 10}{3}$

3(24x-10)=5(-18x+30)

72x-30 = - 99x+150

99x+72x = 150+30

171x = 180

X = 180/171

e)

x+4 = (- 2x-6)/7

7x+28 = - 2x - 6

7x+ 2x = - 6-28

9x = 34

X = 34/9
