i don't kow how to sole this equation 5x-10=2x-7 can u help me

  • 7th grade -

    5x-10-2x+7=0
    3x-3=0
    3x=3
    x=1

  • 7th grade -

    5x-10=2x-7
    Add 10 to both sides.
    5x=2x+3
    Subtract 2x from both sides.
    3x=3
    Divide both sides by 3.
    x=1
    This way is the more common method although Emily did get the correct answer.

  • 7th grade -

    I'm in 7th grade too but I studied this last year so:

    5x-10=2x-7
    -2x -2x
    3x-10= -7
    +10 +10 (because -10 and -7 are -)
    3x = 3 Then divide out
    x=1
