Answer:

18x + 13y = 60

6x + 2y = 6 ---> 6x = -2y +6 ---> 18x = -6y+18

Substitution

(-6y +18)+13y =60

       -18           -18

--------------------------

7y = 42 so y=6

Then, 6x + 2(6) =6, which you will get x = -1

(-1, 6)

Answer:

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).

Tju [1.3M]

Answer:

5/4in

Step-by-step explanation:

The initial length:

1 ft = 12 in

8 ft = 8 * 12 in    

= 96 in

The final length:

7 ft 10 3/4 in = 7 ft + 10 in + 3/4 in

                     = 7 * 12 in + 10 in + 3/4 in                    

                     = 84 in + 10 in + 3/4 in        

                     = 94 in + 3/4 in

The final length:

96 in - 94 in - 3/4 in = 2 in - 3/4 in = 8/4 in - 3/4 in = 5/4 in
