You can put this solution on YOUR website! (2)/(x)+(1)/(x)=3
Find the LCD (least common denominator) of (2)/(x)+(1)/(x)+3.
Least common denominator: x
Multiply each term in the equation by x in order to remove all the denominators from the equation.
(2)/(x)*x+(1)/(x)*x=3*x
Simplify the left-hand side of the equation by canceling the common terms.
3=3*x
Multiply 3 by x to get 3x.
3=3x
Since x is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.
3x=3
Divide each term in the equation by 3.
(3x)/(3)=(3)/(3)
Simplify the left-hand side of the equation by canceling the common terms.
x=(3)/(3)
Simplify the right-hand side of the equation by simplifying each term.
Answer: x=1
