Question

solve the equation 2x+1=x-3and represent the solution (s) on (i) number line (ii) Cartesian plane

Answer 1

$\textbf{ Hello Mate! }$

Equation :

2x + 1 = x - 3

2x - x = - 3 - 1

x = - 4

Now, how can we write it in linear equation with two variable?

1x + 0y = - 4

Let's keep y once 1, 2 and 3.

1x + 0(1) = - 4

x = - 4

1x + 0(2) = - 4

x = - 4

1x + 0(3) = - 4

x = - 4

So coordinates we got,

( - 4 , 1 ) ; ( - 4 , 2 ) ; ( - 4 , 3 )

Have great future ahead!

Answer 2

sir if we are having only x then how can we determine y

please answer I wasn't able to comment that is why I am asking my doubt through the answer corner

I am sorry but its urgent

please forgive me and answer to my question !!!

please
