Best ResponseYou've already chosen the best response.011/a  8/2a = 7 Multiply both sides by a. 11  8/2 = 7a Divide through by 7. 11/7  4/7 = a 7/7 = a 1 = a Hope this helps.

Best ResponseYou've already chosen the best response.1I think seanwalsh misread your equation; he is correct if the second term on the LHS is 8/2a, but not if it is 8/(2a), which is what your drawing looks like to me. In case it is the latter:\[\frac{11}{a}+\frac{8}{2a}=7\]now reduce the 8/2 to a 4\[\frac{11}{a}+\frac{4}{a}=7\]combine like terms\[\frac{15}{a}=7\]or\[a=\frac{15}{7}\]
