Solving for X
Help,
I am trying to solve 3(4x2.8)= 5(4x2.8) for x using the HP Prime. The answer should be X = 0.7. In CAS mode I entered SOLVE( 3(4x2.8)= 5(4x2.8) ) and received Error: Bad Argument Value. Would someone please tell me the steps to accomplish the solution with the HP Prime? Cheers!

There is no implicit multiplication, so your entry needs to be
solve (3*(4*x2.8)=5*(4*x2.8)) Note the lowercase variable usage and the command in lowercase too. Use the Help button too when exploring the commands. HTH, ~Mark Remember kids, "In a democracy, you get the government you deserve."
