Solve this system of linear equation the x- and y-value with a comma. 18x+13y=60 6x+2y=6

The solution is (-1, 6).

Step-by-step explanation:

Rewrite 18x+13y=60 6x+2y=6 as

18x+13y=60

6x+2y=6

and then mult. the 2nd equation by -3:

18x+13y=60

-18x - 6y= -18

Sum up the two equations:

18x+13y=60

-18x - 6y= -18

         7y = 42, so y = 6.

Subbing 6 for y in the first equation results in:

          18x + 13(6) = 60, which can be reduced to 3x + 13 = 10

Then 3x = -3, and x = -1.

The solution is (-1, 6).

option 1

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.

it would be 6xy and -16xy.
