    Which equation? \[A=\frac{ 9 }{ 2 }(x+28)\] or \[A=\frac{ 9 }{ 2(x+28) }\]

    9/2 is in multiplied in front of the parentheses, so you need to multiply both sides by its reciprocal to cancel it out. So multiply both sides by 2/9

    So multiply the 9/2 and the 28 by 2/9?

    now 28 is added to x, so you have to subtract 28 from both sides to get x by itself
