7x + 2y=12
5x+2y=8
(it's a linear equation)

I’m not 100% sure what the question is but I’ll assume it’s to solve the linear system lol.


Answer: (2, -1)




Explanation: To solve a linear system, you must first choose a variable (either X or Y) to eliminate in both equations. In this case, you are already able to eliminate Y by subtracting the equations, because 2y-2y=0. Once you have finished subtracting the equations, it should look like this:

2x=4
x=2

Now that you have the value of x, substitute x=2 into either the first or second equation. As an example, I’ll use the first equation:

7(2)+2y=12
14+2y=12
2y=-2
y=-1

Therefore, the point of intersection of these two lines is (2, -1).


Hope this helps シ

Answer:

If we are solving for x i think its

y= - 5x/2+4

y= -7x/2 +6

I am not sure if its right but hope it helps
