Question

We will use the elimination method to solve the following system of

Answer 1

Answer:

x = 3

y = -5

Step-by-step explanation:

It would be very easy to eliminate y by adding the two equations,

   4x - 7y = 47

   6x + 7y = -17

   10x       = 30

      x = 3                     4(3) - 7y = 47

                                   12 - 7y = 47

                                       -7y = 35

                                          y = -5

Check:  See if the values work in the second equation

6(3) + 7(-5)

= 18 - 35

= -17             It looks like they work, so we know we have the correct values
