(i) 5x – 4y + 8 = 0
7x + 6y-9=0

Answer:
Heya!!
Step-by-step explanation:
What function we have to perform?
Assuming that you need to find x and y values
1. 5x - 4y + 8 = 0 => 5x - 4y = -8 -------------------(1)
2. 7x + 6y - 9 = 0=>7x + 6y = 9 -------------------(2)
We have to make any of the term equal so,
Multiply (1) by 6,
we get , 30x - 24y = -48 ---------------(3)
and Multiplying (2) by 4,
we get, 28x + 24y = 36 ----------------(4)
Adding (3) and (4),
30x - 24y = - 48 ---------------(3)
(+) 28x + 24y = 36 ---------------(4)
----------------------------------------------
58x = -12
=> x = -12/58 = -6/ 29 ------------(5)
Substituting (5) in (1),
5 x -6 /29 - 4y = -8
=> -30/29 - 4y = -8
=> 4y = -30/29 + 8
=> 4y = -30 + 232 /29
=> 4y = 202 / 29
=> y = 202/29 x 4
=> y = 202/116
=> y = 101/58
THEREFORE, VALUE OF x is -6 / 29 and y is 101 / 58
