Answer:
(2, -1)
Step-by-step explanation:
5x + y = 9...........1
3x + 2y = 4.........2
from 1 y = 9 - 5x..........3
put eqn 3 in 2
3x + 2( 9 - 5x) = 4
3x + 18 - 10x =4
-7x = 4 - 18
-7x = -14
x = 14/7
x =2
put the value of x in equation 3
y = 9 - 5(2) = 9 -10 = -1
x = 2 and y = -1
I hope this helps. I used the substitution method
