Question

6x-4y=8
4x+20=0
Please help me guys
​

Answer 1

Answer:

6x-4y=8

3x -2y =4.........(i)

4x+20y=0

x+5y = 0........(ii)

x= -5y......(iii) ( from (II))

putting x = -5y in i

3×(-5y) -2y = 4

-15y -2y = 4

-17 y = 4

y = -4/17

putting y = -4/17 in iii

x = -5 ×-4/17

x = 20/17

so, x= 20/17

y = -4/17
