What is the solution of the system x − 3y = –13 and 5x + 7y = 34?

(1/2, 9/2)

Step-by-step explanation:

Write the system as a column (not as a row of characters):

x − 3y = –13 and 5x + 7y = 34 =>

x − 3y = –13

5x + 7y = 34

Let's eliminate x using the method of addition and subtraction.  Multiply all terms of the first row by -5:

-5x + 15y = 65

5x + 7y = 34

The sum of these two equations is

         22y = 99, and so

               y = 9/2

Substituting 9/2 or y in the first equation, we get:

   x - 3(9/2) = -13, which simplifies to:

   x               =  27/2 - 13, or

   x               =  27/2 - 26/2, or x = 1/2

Then the solution is (1/2, 9/2)

step-by-step explanation:

its a wood chuck that can chuck wood

it has the same slope and a different y-intercept

hope this : )
