Question

8x - 3(2x - 4) * - 9

Answer 1

Answer:

x = 54/31

Step-by-step explanation:

Solve for x:

8 x + 27 (2 x - 4) = 0

27 (2 x - 4) = 54 x - 108:

54 x - 108 + 8 x = 0

Grouping like terms, 54 x + 8 x - 108 = (8 x + 54 x) - 108:

(8 x + 54 x) - 108 = 0

8 x + 54 x = 62 x:

62 x - 108 = 0

Add 108 to both sides:

62 x + (108 - 108) = 108

108 - 108 = 0:

62 x = 108

Divide both sides of 62 x = 108 by 62:

(62 x)/62 = 108/62

62/62 = 1:

x = 108/62

The gcd of 108 and 62 is 2, so 108/62 = (2×54)/(2×31) = 2/2×54/31 = 54/31:

Answer:  x = 54/31
