Solve 5-4/5x=-11
check please to see what I did wrong?
5-4/5x= -11 + 5
-4/5x= -6
-4/5x= -6 -4/5
x=-6/1 - 5/4
x=-30/4
x=-7 1/2

\[\frac{5-4}{5x}=-11\]?
OpenStudy (anonymous):
at step 3 multiply by -5/4 to cancel the coefficient in the x term. then work from there
OpenStudy (anonymous):
\[\frac{1}{5x}=-11\]
OpenStudy (anonymous):
5x*-11=1
OpenStudy (anonymous):
-55x=1
x=1/-55

30-5>-x+3x
25 > 2x
25/2>x

hey can u check this for me please
5/9(x) >= - 3/4
5/9-5/9(x) >= - 3/4 -5/9
x>= -3/4(9)-5/9(4)
x>= -27/36 - 20/36
x>=-7/36
the answer is x>= -7/36
