Question

find the value of x and y by substitution method​

Answer 1

Answer:

Step-by-step explanation:

8x + 5y = 9 3x + 2y = 4

3x = 4 - 2y

x = (4 - 2y)/3

8(4 - 2y) /3 + 5y = 9

32 - 16y + 15y = 27

- y = 27 - 32

y = 5

x = (4 - 2y)/3

x = {4 - 2(5) } /3

x = - 6/3

x = - 2

therefore x = - 2 ; y = 5
