The solution to the system of equations is given as follows:
x = 1 and x = 3.
<h3>What is a system of equations?</h3>A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the two equations are:
Applying cross multiplication:
(x - 2)(x - 2) = 1
x² - 4x + 4 = 1
x² - 4x + 3 = 0
(x - 1)(x - 3) = 0
Hence the solutions are:
- x - 1 = 0 -> x = 1.
- x - 3 = 0 -> x = 3.

Okay, so first you are going to decide whether to solve for x or solve for y. I am going to solve for x. In order to do so, you must get x by itself.
![2x=y-6[ [tex]3x-4y=-4](https://tex.z-dn.net/?f=2x%3Dy-6%5B%20%5Btex%5D3x-4y%3D-4)
The next step is to set both equations equal to each other in order to find y.
\frac{y-
6}{2} [/tex]
So now you know that y=-2. The next part is substitution. All you have to do is pick on of the equations and plug in the y value to get the x value.
So your answer to the question is (-4,-2). I hope I've helped you understand how to solve these types of problems. If you have any questions, don't hesitate to ask.

Answer:
y=-
Step-by-step explanation:
Slope intercept form is y=mx+b. So, you solve for y by putting x to the other side and dividing by 6. In order it looks something like:
2x+6y=36
2x -2x +6y = 36 =2x
6y=36-2x
y=6-2/6x
y=6-1/3x
