Correct Answer

Explanation

To solve the equation y + 1/2 - 2y - 1/3 = 4, we can simplify the equation and then solve for y.Combining like terms, we have:(1/2) - (1/3) + y - 2y = 4To simplify the left side of the equation, we need to find a common denominator for 1/2 and 1/3, which is 6. (3/6) - (2/6) + y - 2y = 4Simplifying further, we have:(1/6) - y = 4To isolate y, we can subtract (1/6) from both sides:-y = 4 - (1/6)To combine the terms on the right side, we need a common denominator:-y = (24/6) - (1/6)-y = 23/6Finally, we can solve for y by multiplying both sides by -1:y = -23/6Therefore, the solution to the equation y + 1/2 - 2y - 1/3 = 4 is y = -23/6.
