Question

Determine whether x=1 and y=10 is a solution to the equations


`x + 3 = 30 \\ \\ 2x - y = 9`


​

Answer 1

They are not solutions

Explanation:

To see if it is correct we have to substitute the variables for the numbers given.

x+3=30

1+3≠30

2x-y=9

2·1-10≠9

So, these solutions would be incorrect.
