Question

Indicate whether (4, 12) is a solution of the given system.

Answer 1

Given:

The system is:

`\begin{gathered} y\leq x \\ \\ y>x+3 \end{gathered}`

The solution set (4,12)

Find-:

(4,12) is the solution for the system

Explanation-:

The solution set is:

`=(4,12)`

That men the value x =4 and y = 12.

Check for the system is:

`\begin{gathered} y\leq x \\ \\ 12\leq4 \end{gathered}`

If it is not a solution then check another part of the system is:

`\begin{gathered} y>x+3 \\ \\ 12>4+3 \\ \\ 12>7 \end{gathered}`

The system is a solution (4,12) is agreed.

Yes, (4,12) is a solution of the system
