Question

8x+5y=9
3x+2y=4
substitution method
​

Answer 1

Answer:

8x + 5y = 9. 3x + 2y = 4. So, the solution of the given pair of linear equations is x = -2,y = 5. Hence, the required solution of the given pair of linear equations is x = -2, y - 5.

Answer 2

Answer:

8x+5y=9

3x+2y=4

8x=9-5y

x=9-5y /8

now putting value of x in 3x+2y=4

we have

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

27-15y/8+2y=4

27-15y+16y/8=4

27+y=32

y=5

3x+2y=4

3x+10=4

3x=-6

x=-2
