Question

Which ordered pair is a solution of the system of the 2 equations: 3x + 2y = 4 and -x + 3y = -5 ?


A. (2, -1)
B. (-2, 1)
C. (-3, 2)
D. none of the above

Answer 1

Find x from 2nd equation :

x = 3y + 5

Put it in other equation :

3x + 2y = 4

3(3y + 5) + 2y = 4

Solving this,

11y = -11

y = -1 and x = 2..

So, you know now what is the right option???

Answer 2

A
