if y=5x-2, then -3x=? PLEASE EXPLAIN
a 5x -6
b 15x-6
c 15x+6
d -15-6
e -15x+6

  • math -

    if y = 5x -2 then
    5x=y+2 and
    x = (y+2)/5, then
    3x = 3(y+2)/5 and
    -3x = -3(y+2)/5 which unfortunately is not one of your answers.

    Did you make a typo?
    did you mean find -3y ???
    then it is even easier, just follow my steps.
