Answer:
15/8
Explanation:
Please use the letter " x " here instead of the multiplication operator " × ."
Your 1/2× +3/2(×+1)-1/4=5 is best written as
(1/2)x +(3/2)(x + 1) - (1/4) = 5
Perform the indicated multiplication. We get:
(1/2)x +(3/2)x + 3/2) - (1/4) = 5
The first two terms combine to yield 2x, so that the equation is now
2x + 3/2 - 1/4 = 5
The LCD is 4. Multiplying all terms by 4, we get:
8x + 6 - 1 = 20, or 8x + 5 = 20.
Simplifying this further, we get 8x = 15, so that
x = 15/8
