Question

solve pairs of linear equation by eliminating substitution. 8x + 5y = 9
3x + 2y = 4​

Answer 1

Answer:

Step-by-step explanation:

given here

8x +5y = 9.......(1)

3x +2y = 4........(2)

Solve by[ substitution method]

by (2),

3x = 4-2y

=>x = (4-2y)/3......(3)

keep in (1),

we get,

8 × (4-2y)/3 +5y = 9

=> 32-16y + 15 = 27

=> -16y = 27-47

=> y = 20/16

=> y = 5/4

keep in (3),

x = (4-2×5/4)3

= (4-5/2)/3

= (8-5)/6

= 3/6

= 1/2

✒Thus:-

Value of x = 1/2

value of y = 5/4
