Solution:

2/x     +  y/4     =    3/2

Let's solve for y.

2/ x    +   y/ 4    =     3/ 2

Step 1: Multiply both sides by 4x.

xy     +    8    =     6x

Step 2: Add -8 to both sides.

xy    +    8    +    −   8    =    6x    +    −8

xy    =   6x   −    8

Step 3: Divide both sides by x.

xy/x     =       6x    -    8/x

Answer   =====>  y   =    6x     -   8/x




When Graph:  

y     =     6    -   8/x

x- Intercepts Points:

4/3,    and       0




Equation====>  2:

Let's solve for x.

2/ x      +    y/ 4     =      3/ 2

Step 1: Multiply both sides by 4x.

xy     +    8     =    6x

Step 2: Add -6x to both sides.

xy    +    8    +    − 6x    =     6x     +     −  6x

xy    −     6x    +    8    =    0

Step 3: Add -8 to both sides.

xy     −     6x    +    8    +    −    8      =     0    +       −8

xy     −    6x      =   −8

Step 4: Factor out variable x.

x(y   −   6)    =    −8

Step 5: Divide both sides by y-6.

x( y   -    6 )/y   -  6       =        -8/ y    -   6

Answer  ======>      x     =       -8/y    -   6







Hope that helps!!!!                                  : )
