Two systems of equations are shown below. the first equation in system b is the original equation in system a. the second equation in system b is the sum of that equation and a multiple of the second equation in system a.
a. 1/2x + 3y = 11 → 1/2x + 3y = 11
5x − y = 17 → 15x − 3y = 51
15 1/2x = 62
b. 1/2x + 3y = 11
151/2x = 62
answers
a=(3,4)
b=(3,5)
c=(4,3)
d=(5,3)
