Correct homework.

Solving Systems of Linear Equations by Combination or Elimination Problem 4.3

A2 4x + 2y = 6 -3x - 7y

= 1{

3. x - y = -5

-x + 4y = 10

{

{4. 3x + y = 4

6x + 2y = 7

{

5 3x + 2y = 10

-6x - 4y = -20

5 3x + 2y = 10

-6x - 4y = -20

{6 x + y = 13

x - y = 2

Notice anything different about some of the systems?

Complete then discuss.
