Question

8x+5y=9;2y=-3×+4 solve by substitution method
​

Answer 1

Step-by-step explanation:

To solve the linear equations 8x + 5y = 9 ... (i) and 3x + 2y = 4 ...

(ii)

From (i), we have

X

9 - 5y

8

(iii)

Substituting the value of x in (ii), we get

9-5y 3x +2y =4

> 27 – 15y + 16y=32

> y=32 - 27 = 5

Substituting y in (iii), we get

9-5 X 5

X =

8

-16

8

Hence, x= – 2 and y=5 is the solution of the given linear e
