Answer:
x = -4/13
Explanation:
Solve 2/3x - 1/3 = 2 (x + 2).
Rewrite this as (2/3)x - 1/3 = 2 (x + 2) to reduce ambiguity.
Eliminate fractions, first by multiplying all terms by 3:
2x - 1 = 6(x + 2).
Perform the indicated multiplication, so as to be able to combine like terms:
2x - 1 = 6x + 12
Combining like terms, -13 = 4x
Solving for x: x = -4/13
