-\frac{9x}{4}=27

IRISSAK [1]

$\bf \cfrac{-9x}{4}=27\implies \stackrel{\textit{cross multiplying}}{-9x=4(27)}\implies x=\cfrac{4(27)}{-9}\implies x=4\cdot \cfrac{27}{-9} \\\\\\ x=4\cdot -3\implies x=-12$

Write Y+2=1/3x in standard form

solong [7]

The standard form of a line is in the form

$Ax + By = C$

A, B and C are integers, and A is positive. Let's start with multiplying the whole equation by 3 to get rid of denominators:

$3y+6=x$

Subtract 3y from both sides:

$6=x-3y$

Which of course is equivalent to

$x-3y=6$

Which is the standard form, given the coefficients A=1, B=-3, C=6.
