Question

Using systems of equations, what is the answer for:y= x+1 y=2 x-1

Answer 1

Answer : The value of x and y is, 2 and 3 respectively.

Explanation :

The given equations are:

$y=x+1$      .........(1)

$y=2x-1$    ..........(2)

Using substitution method:

Now we are putting the equation 2 in 1, we get the value of 'x'.

$2x-1=x+1$

$2x-x=1+1$

$x=2$

Now we are putting the value of 'x' in 1, we get the value of 'y'.

$y=x+1$

$y=2+1$

$y=3$

Thus, the value of x and y is, 2 and 3 respectively.
