solve by using multiplication principle

-3/7x=6/35

x=______________

  • algebra -

    -3/7x = 6/35
    to get x alone, you must divide all terms by the numerical coefficient (the number before the variable) of x, thus:
    (-3/7)x/(-3/7) = (6/35)/(-3/7) = -(6/35)/(3/7)
    *i just rewrite the negative sign outside*
    on the left side, -3/7 will be cancelled, and on the right side, we have a to divide fractions,,
    to divide a fraction, first get the reciprocal of the divisor (the 3/7),
    reciprocal is just interchanging of numerator and denominator:
    3/7 : reciprocal is 7/3
    now, the process becomes multiplication:
    x = - 6/35 * 7/3
    multiply numerator by numerator, and denominator by denominator:
    x = -(6*7)/(35*3)
    now solve for x,,

    hope this helps. :)
