Solving for X
Help,
I am trying to solve -3(4x-2.8)= -5(4x-2.8) for x using the HP Prime. The answer should be X = 0.7. In CAS mode I entered SOLVE( -3(4x-2.8)= -5(4x-2.8) ) and received Error: Bad Argument Value. Would someone please tell me the steps to accomplish the solution with the HP Prime? Cheers! |

RE: Solving for X
There is no implicit multiplication, so your entry needs to be
solve (-3*(4*x-2.8)=-5*(4*x-2.8)) 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." |
