Question

X=y+2
X=2y+1

Solving Systems of Equations by subtraction
Please solve this

Answer 1

`x=3`

`y=1`

Explanation:

We can subtract the first equation from the second to find the value of
`y`, although we can also do this vice versa.

`x-x=2y+1-y-2`

`y-1=0`

`y=1`

Now, we can use substitution to solve for
`x`:

`x = y+2` (pick any equation for substitution)

`x=1+2`

`x=3`

Hope this helps :)
