Solving systems of equations algebraically.
Elanso [62]

Answer:

x = 2

y = -1

Step-by-step explanation:

Since it gives you the value of y already, just plug that into the equation, like so:

y = 4x - 9

x - 3 = 4x - 9

<em><u>Subtract the x from both sides:</u></em>

x - 3 = 4x - 9

-x       - x

__________

-3 = 3x - 9

<em><u>Then, add 9 to both sides:</u></em>

-3 = 3x - 9

+9        + 9

________

6 = 3x

<em><u>Divide both sides by 3:</u></em>

2 = x

<em><u>Now plug in x for y:</u></em>

y = x - 3

y = 2 - 3

y = -1

​3 ​/​10 ​​ = ​9 /​k ​​ what is k
NemiM [27]
In order to isolate k, we would first cross multiply
3*k=9*10
3k=90

Then to isolate k, we would divide both sides by 3 to get:
K=30

Hope this helps
