Wich method would be the simplest way to solve the system 7X+5y=19 - 7X-2y=-16. A - graphing B - substitution C - elemination D - distributive?

C - elemination or reduction

Method of elimination or reduction

Adding two equations is to obtain a new equation whose right (left) member is the sum of the right (left) members of the equations that are added together.

7X+5y=19

-7X-2y=-16.

Adding two equations

3y=3 - - - > y=1

then

7x+5 (1) = 19

7x=19-5

x=14/7=2
