x=______________

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. :)
