8x - 4y = -12 solve for y

son4ous [18]

Solving an equation means finding a value of a variable that make the equation true. This value is called the solution of the equation. A mathematical equation is just like a balanced equation. Both sides of the equation should be equal at all times. Whatever we do to one side, has to be done on the opposite side.

$8x - 4y = -12$

$4(2x-y)=-12

 
$ $Factor \ out \ the \ common \ term \ 4$

$2x-y=- \dfrac{12}{4}$ $Divide \ both \ sides \ by \ 4$

$2x-y=-3

 

$

$-y=-3-2x$ $Subtract \ 2x \ from \ both \ sides$

$y=3+2x$ $Multiply \ both \ sides \ by \ -1$

a student was given the equation x^2+6x-13=0 the next step in the students process was x^2+6x+c=13+c state the value of c that c

Ratling [72]

This is the process of completing the square.
Keep this equation in mind: $ax^2+bx+c$
Basically, to make this a perfect square trinomial, you take half of b and square that value. This will make it so you can compress the left side of the equation into $(x+b)^2 \ or \ (x-b)^2$ depending on the sign in the middle of the original equation.
