2x + y = 3
x - 2y = -1

if equation one is multiplied by 2 and then the equations are added, the result is

If equation one is multiplied by 2 and then the equations are added, the result is x=1.

The first equation is given by:

and the second equation is given by:

Now on multiplying first equation by 2 we get:

and now on adding this equation to equation (2) we get:

Now on combining the like terms we get:

and on putting the value of x back to the equation (2) we get:

2

step-by-step explanation:
