multiply both sides by the reciprocal of the coefficient of x:
(-7/4)(-4/7)x=(-7/4)(2/5)
x=(-7/10)

-4/7*x=2/5
now you have to divide each side by -4/7
-4/7/-4/7*x=2/5/-4/7
now to divide a fraction you take the reciprical of the second fraction and multiply so you have:
x=2/5*7/-4
this is what you get..
x=14/-20
simplified...
x=-7/10
now plug back into the solution and remember a negative*negative=positive
-4/7*-7/10=
28/70=14/35=2/5
so this solution works so the answer is
-7/10 or -.7
check ya later â¥
