Question

4x- 3y=8 and 3x+6y= 23
{ by elimination method}​

Answer 1

Answer:

4x-3y=8………(i)

3x+6y=23………(ii)

Solve equation (i)

4x-3y=8

4x=8+3y

x=8+3y/4

Put the value of (x=8+3y/4) in equation (ii)

3x+6y=23

3(8+3y/4)+6y=23

24+9y/4+6y=23

9y/4+6y=23-24

9y+24y=-1

_____

4

cross multiplication

9y+24y=-4

33y=-4

y=-4/33
