Okay so I need to know the standard form of these linear equations! please. I just need the answers to check mine. This is stressing me out.
1)8X-3y=6-4x 2)7x+y+3=y 3) 5-2y=3x
4)x/4-y/3=1 5)5/x-2/y=7

1)  8X-3y = 6 - 4x

The standard form of the eqations is  ax+by+c=0

Now add 4x to each side

8X - 3y + 4x = 6 - 4x + 4x

12x - 3y = 6

Subtract 6 from each side

12x - 3y -6 = 6 - 6

12x - 3y -6 = 0

The standard form of the given linear equation is 12x - 3y -6 = 0

2) 7x + y + 3= y

The standard form of the eqations is  ax+by+c=0

Subtract y  from  each side

7x + y + 3 - y = y - y

7x + 3 = 0

The standard form of the given linear equation is 7x + 3 = 0

3)  5 - 2y = 3x

The standard form of the eqations is  ax+by+c=0

5 - 2y + 2y = 3x +2y

5  = 3x +2y

Subtract  5 from each side

5 - 5  = 3x +2y -5

0 = 3x +2y - 5

3x +2y - 5 = 0

The standard form of the given linear equation is 3x +2y -5 = 0

4)   x/4 - y/3 =1

LCM of 4 and 3 is 12

(3x -4y)/12 = 1

Multiply each side by 12

3x  - 4y = 12

Subtract 12 from each side

3x  - 4y -12 = 12 -12

3x  - 4y -12 = 0

The standard form of the given linear equation is   3x  - 4y -12 = 0

5)     5/x-2/y=7

The standard form of the eqations is  ax+by+c=0

LCM of x and y is xy

(5y-2x)/xy = 7

5y - 2x = 7xy

Multiply each side by negative one.

2x -5y = -7xy

2x - 5y +7xy =0

Here the conversion of standard formation ax+by+c=0 is not possible
