Hello I need help with this problem. I need to identify if the equation is identity, contradiction, or conditional equation.


-(5x-3)+2x=11-4(x+2)

  • College Algebra - ,

    -(5x-3)+2x=11-4(x+2)
    -5x+3+2x=11-4x-8
    -3x+3=3-4x
    (try to make "x" positive here, so add 4x to both sides of the = sign and subtract 3 from both sides as well. doing this will end you with "x=0" which is the answer. but make sure you check that the solution works in the problem (just substitute 0 for the "x"'s in your original problem to show your work.)

    I also had x=0 but I'm confused if its a identity, contradiction, or conditional equation
