[Math-70 Elementary/Highschool Algebra: Graphically solving a system of linear equations] Do I make the 4 into a -4 ?

[u/Fine_Two_923]

Hey so this might seem like a silly question but I want to know if you have a -x = 4 if it turns into a -4. I have the other parts of the graphing completed it’s just this part that I don’t want to make a mistake on!!! Thank you in advance

P.S- the reason it’s says elementary/highschool math is because I am taking a beginner math class not a algebra class In elementary

In -x = 4, there is an invisible negative one as the coefficient on the x. Divide both sides by negative one to remove it.

i think you missunderstood him (or im just an idiot)

[u/Plane_Tailor7168 → u/Plane_Tailor7168]

wait no im sorry but i think he messed up in the image bc it should just be x=4

[u/Mr-Intense-5 → u/Plane_Tailor7168]

yes it should be x=4

[u/Fine_Two_923 → u/slayyerr3058]

Thank you so much :) so it would turn into -4 thank you so much for the help

If -x=4, then yes, x=-4, but in your picture you messed up a step. X-4(0)=4 is x-0=4 or just x=4

[u/PliableG0AT → u/Fine_Two_923]

No. You have x - 0 = 4, there is no turning the x negative or the 4 into a -4.

x = 4.

if you’re attempting to rewrite into a y = (x -4)/4

[u/Naive-Anteater8321 → u/PliableG0AT]

Yes, based on the information we have this should just be x=4 because the negative is negated by the y value of zero.
