Assuming you mean isolate for x

Answer:

$x=-1$

Step-by-step explanation:

We can subtract $4x$ from both sides to get $3x-4x=4x-4x+1$ .

That simplifies to $-x=1$ .

We can multiply by $-1$ to get $-x*-1=1*-1$ .

That simplifies to $x=-1$ .

So, $x=-1$ and we're done!

SIMPLIFY (81/16}-3/4 X {(25/9)-3/2 DIVIDED BY (5/2)-3}

babymother [125]

$(\frac{81}{16} - \frac{3}{4} )( \frac{\frac{25}{9}- \frac{3}{2}}{ \frac{5}{2} -3}) = \frac{-529}{48}$

If I understood correctly and didn't make any mistakes...

Answer:

$\frac{31x}{30}$

Step-by-step explanation:

Before adding we require the fractions to have a common denominator

The lowest common denominator of 2, 5 and 3 is 30, thus

$\frac{15x}{15(2)}$ + $\frac{6x}{6(5)}$ + $\frac{10x}{10(3)}$

= $\frac{15x}{30}$ + $\frac{6x}{30}$ + $\frac{10x}{30}$

Add the numerators leaving the denominator

= $\frac{15x+6x+10x}{30}$ = $\frac{31x}{30}$
