Question

I’m slow and lazy and yeah sorry just at least help

Answer 1

Answer:

2) x = 6    y = 7      3) x = -5    y= 2

Step-by-step explanation:

2) 10x - 8y = 4

   2(-5x + 3y = -9)

-10x + 6y = -18

 10x - 8y =   4      Add both equations together

         -2y = -14

         y = 7            Divide both sides by -2

10(x) - 8(7) = 4       Plug in 7 for the y to solve for x

10x - 56 = 4  

     + 56 + 56        Add 56 to both sides

10x = 60

x = 6                      Divide both sides by 10

3) Where the two lines intersect, that is the solution to x and y.

The lines intersect at (-5,2). x = -5      y = 2
