First, distribute the -3 on the right side. Then multiply both sides by the LCD to get rid of fractions. Then collect like terms.

LCD is 4??

The LCD is the smallest number that 2, 3, and 4 divide _into_ evenly, so it can't possibly be smaller than 4.

(1)/(3)*x+(1)/(2)=-3((3)/(4)*x-1) Multiply (1)/(3) by x to get (x)/(3). (x)/(3)+(1)/(2)=-3((3)/(4)*x-1) Multiply (3)/(4) by x to get (3x)/(4). (x)/(3)+(1)/(2)=-3((3x)/(4)-1) Multiply -3 by each term inside the parentheses. (x)/(3)+(1)/(2)=-(9x)/(4)+3 Since (1)/(2) does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting (1)/(2) from both sides. (x)/(3)=-(1)/(2)-(9x)/(4)+3 Simplify the right-hand side of the equation. (x)/(3)=-(9x)/(4)+(5)/(2) Find the LCD (least common denominator) of (x)/(3)-(9x)/(4)+(5)/(2). Least common denominator: 12 Multiply each term in the equation by 12 in order to remove all the denominators from the equation. (x)/(3)*12=-(9x)/(4)*12+(5)/(2)*12 Simplify the left-hand side of the equation by canceling the common factors. 4x=-(9x)/(4)*12+(5)/(2)*12 Simplify the right-hand side of the equation by simplifying each term. 4x=-27x+30 Since -27x contains the variable to solve for, move it to the left-hand side of the equation by adding 27x to both sides. 4x+27x=30 Since 4x and 27x are like terms, add 27x to 4x to get 31x. 31x=30 Divide each term in the equation by 31. (31x)/(31)=(30)/(31) Simplify the left-hand side of the equation by canceling the common factors. x=30/31

LCD (= least common denominator) is also called the LCM (= least common multiple). What number is the smallest multiple of 2, 3, and 4? Here are the first several multiples of 2, 3, and 4. Pick the smallest common one: 2: 2, 4, 6, 8, 10, 12, 14, 16, 18 3: 3, 9, 12, 15, 18, 21 4: 4, 8, 12, 16, 20, 24

Multiply each side by 12.\[12\left(\frac{1}{3}x+\frac{1}{2}\right)=\left(-3\left(\frac{3}{4}x-1\right)\right)12 \]\[4 x+6=36-27 x \]
