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

Answered by hiramani7080

7y+21-2x-4=14

7y-2x=14+4-21

7y-2x=18-21

7y-2x=-3--------(1)*3

4y-8+3x-9=2

4y+3x=2+9+8

4y+3x=19-------(2)*2

On adding both equation (1) & (2) we get:-

21y-6x=-9

8y+6y=38

--------------------

29y=29

y= 1

Therefore putting the value of y=1 in equation (2) we get :-

4y+3x=19

4+3x= 19

3x= 19-4

3x= 15

X= 5

Hence, X= 5 & y=1

1)7y+21-2x-4=14

=7y-2x=14-17

=7y-2x=-3

let let y be 1 and x be 5

7(1)-2(5)=-3

7-10

=-3=-3

lhs=rhs

2)4y-8+3x-9=2

4y+3x=2+17

4y+3x=19

lhs not equal to rhs

shahifits: wrong

dheemanth41vbcih: its correct u r wrong

dheemanth41vbcih: if u know the answer then why asked question

hiramani7080: shahifits it's correct dear he just calculated the value of x and y then checked his calculation
