Hello, jeilynn,

I would choose B because

- you can easily solve the second equation for x: The coefficient of x is (+1)

- you can substitute the term for x in the first equation

5x + 3 y = 3

x + 9y = 2 ==> x =2 - 9y

5(2-9y) + 3y = 3

10 - 45y + 3y = 3

-42y = -7

y = 1/6Now substitute this result into the equation which expresses x:

x= 2 - 9*(1/6) = 2 - 3/2 =1/2
