Question

How do you solve the system `x=2` and `2x+y=1`?

Answer 1

Given `x=2`
we can substitute `2` for the variable `x` in the second equation:
`2x+ y =1`
giving
`2(2) + y = 1`
`rarr y= -3`

So `(x,y) = (2,-3)`

Answer 2

Simply u have to put x=2 in the given equation and u can find the value of y.

• In this equation,
  putting x=2,we get
  `2(2)+y=1`,
• now,solve the equation,and u get
  `y=-3`
• so now,x=2
  and y=-3.

Thank u!
