Solve an algebraic expression with fractions.
(x + 3)/6 = 2/3. First, cross multiply to get rid of the fraction. ...
(x + 3) x 3 = 2 x 6 =
3x + 9 = 12. Now, combine like terms. ...
3x + 9 - 9 = 12 - 9 =
3x = 3. Isolate the variable, x, by dividing both sides by 3 and you've got your answer.
3x/3 = 3/3 =
x =1.
