Answer:
x = 13/3 or 4.3 repeating (4.333333.....)
Explanation:
3x + 2(4x - 6) = 8x + 1
3x + 8x - 12 = 8x + 1 (expand using distributive property)
11x - 12 = 8x + 1 (combine like terms)
11x - 12 + 12 = 8x + 1 + 12 (add 12 to both sides)
11x = 8x + 13 (simplify)
11x - 8x = 8x - 8x + 13 (subtract 8x from both sides)
3x = 13 (simplify)
3x/3 = 13/3 (divide both sides by 3)
x = 13/3 or 4.3 repeating (4.333333.....)
