Question

solve for x and you 2x +6=6 and x - y= 3​

Answer 1

Step-by-step explanation:

2x+6y = 6

x-y = 3

x+y = 3 (divided by 2)

x-y = 3

2x = 6

x = 3

3-y = 3

y = 0

Answer 2

x = 3 and y = 0

Step-by-step explanation:

The given equations are:

2x + y = 6                           ........... (1)

and x - y = 3​                       ........... (2)

To find, the values of x and y = ?

Adding equations (1) and (2), we get

2x + y + x - y = 6 + 3  

⇒ 3x = 9

⇒ x = 3

Put x = 3 in equation (1), we get

2(3) + y = 6

⇒ 6 + y = 6

⇒ y = 6 - 6 = 0

∴ x = 3 and y = 0
