Let us multiply eq② with 3
➙ 6x - y = × 3
18x - 3y = 29
4x - 3y = 8
- + -
----------------
14x = 21
----------------
➙ x =
➙ x =
Putting x value in eq①
➙ 4 × - 3y = 8
➙ 6 - 8 = 3y
➙ -2 = 3y
➙ y =
Hence
SOLUTION:-
Given
▪︎ 4x-3y=8
▪︎ 6x-y=29/3
To find
Value of x and y
Explanation
▪︎ 4x-3y=8___________(1)
▪︎ 6x-y=29/3___________(2)
Firstly, Take eq 2
▪︎6x-y=29/3
= 6x-y-29/3=0
Take LCM
18x-3y=29_______(3)
On Subtracting eq1 form 3
18x - 3y = 29
4x - 3y = 8
- + -
__________
14x = 21
x=21/14
x= 3/2
Putting value of x in eq 3
▪︎ 18x-3y=29
= 18×3/2-3y=29
= 27-3y=29
= -3y=29-27
= -3y= 2
= y= -2/3
So the value of x = 3/2 and y= -2/3
