2x + y =-3

Explanation:

Standard Form for writing down a Linear Equation is:

color(red)"A"x + color(blue)"B"y = color(green)"C"

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

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

y=2x-3 to standard form:

Bring 2x to the left side

-2x-y=3

Multiply all by -1

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

2x + y =-3

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