Question

8х +5y=9
3x+2y = 4,solve these by substitution and elimination method​

Answer 1

Answer:

Explanation:

Hi friend,

By elimination method :

8x+5y = 9---------(1) ×2

3x+2y = 4 -----(2). ×5

we get,

16x+10y = 18

15x+10y= 20

subtracting both the equations we get;

x = -2

Putting the value of x in (1)...

8×-2 +5y = 9

-16+5y = 9

5y = 9+16

5y = 25

y = 25/5

y = 5

Hope this helped u...
