Umbra Posted July 28, 2009 Report Share Posted July 28, 2009 I'm assuming you mean that f(x) = 2 in the question itself. f(x) = -9x + 5(insert the value 2 into f(x))2 = -9x + 5(subtract 2 on both sides.)0 = -9x + 3(add 9x to both sides.)9x = 3(divide by 9)x = 1/3 Link to comment Share on other sites More sharing options...

Guest Posted July 28, 2009 Report Share Posted July 28, 2009 The "If" is an expression rather than an equation, which means it is completely meaningless as a statement. Link to comment Share on other sites More sharing options...
