2x + y =-32x+y=3

Explanation:

Standard Form for writing down a Linear Equation is:

color(red)"A"Axx + color(blue)"B"Byy = color(green)"C"C

  • color(red)"A"A shouldn't be negative,color(red)"A"A and color(blue)"B"B shouldn't both be zero, and color(red)"A"A, color(blue)"B"B and color(green)"C"C should be integers.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

y=2x-3y=2x3 to standard form:

Bring 2x to the left side

-2x-y=3

Multiply all by -1

I
Icolor(red)"A"A color(darkblue)"mustn't be negative"mustn't be negative

2x + y =-32x+y=3

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Note:
color(red)"A"A=2=2
color(blue)"B"B=1=1
color(green)"C"C=-3=3
