Question

Whether `(2,2)` is a solution to the equations `3x-y=4` and `2x+y=1`?

Answer 1

No.

Explanation:

To check whether `(2,2)` is a solution to given set of equations or not, one need to put the values `x=2` (the first number) and `y=2` (the second number) in each equation and check whether they are satisfied or not.

In the first equation `3x-y=4`, we have

`3xx2-2=6-2=4`, hence this is satisfied.

But for `2x+y=1`,

we get `2xx2+2=4+2=6` and not `1`

hence second equation is not satisfied.

As for `(2,2)` to be solution for system of equations, it should satisfy both the equations, answer is No.
