8x - 3y = 5 is the standard form of equation.

Explanation:

7 - 3(x-y) = 5x + 2

Standard form of linear equation is Ax + By = C

7 - 3x + 3y = 5x + 2

5x + 3x - 3y = 7 - 2

8x - 3y = 5 is the standard form of equation.

3y-8x=-5

Explanation:

Standard form will be ax+by=c or by+ax=c
Hence simplify the given equation first.

7-3(x-y)=5x+2

Open the brackets:

7-3x+3y=5x+2

Subtract 7 both sides:

7-7-3x+3y=5x+2-7

-3x+3y=5x-5

Subtract 5x both sides:

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

-8x+3y=-5

Re-arranging and we get:

3y-8x=-5

Hope this helps!
