PLEASE HELP ASAP!!!

Which is a solution to the following system of inequalities?
4x - 3y<9
x+3y>6

А(-2, 1)

B(3, 1)

C(0,4)

D(1,1)

Answer 1

B.

Explanation:

its the same as saying..

4x - 3y = 9

x + 3y = 6

add both equation together

5x = 15

i.e X = 3

substitute x= 3 in equation 2

3 + 3y = 6

3y = 3

divide both sides by 3

y = 1
