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

May 22, 2015

Given $x = 2$
we can substitute $2$ for the variable $x$ in the second equation:
$2 x + y = 1$
giving
$2 \left(2\right) + y = 1$
$\rightarrow y = - 3$

So $\left(x , y\right) = \left(2 , - 3\right)$

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
$2 \left(2\right) + y = 1$,
• now,solve the equation,and u get
$y = - 3$
• so now,x=2
and y=-3.

Thank u!
