Question

2x+y-6=0 and 4x-2y-4=0​

Answer 1

Answer:

Step-by-step explanation:

   2x + y - 6 = 0

=>2x + y = 6

=>2x = 6 - y

=>x = (6-y)/2  -----------------> (i)

Putting (i) in the second equation

  4 * (6-y/2) - 2y - 4 = 0

=>2(6-y) - 2y = 4

=>12 - 2y - 2y = 4

=> -4y = 4 - 12

=> -4y = - 8

=>y = -8/-4

=>y = 2

Putting y=2 in the first equation

   2x + 2 - 6 = 0

=>2x = 6 - 2

=>2x = 4

=>x = 4/2

=>x = 2

Answer 2

Step-by-step explanation:

2(2x+y–6 = 0)

4x+2y–12 = 0

4x–2y–4 = 0

____________

8x = 16

x = 2

value of x put in in second equation

4x–2
