Step 1:

The linear equations are $\"\"$ and $\"\"$ .

Graph:

Graph the equations $\"\"$ and $\"\"$ .

$\"\"$

Observe the graph:

The graph appear to intersect point at $\"\"$ .

Step 2:

Check the solution for algebraically.

Substitute intersect point $\"\"$ in the linear equation $\"\"$ .

$\"\"$

Substitute intersect point $\"\"$ in the linear equation $\"\"$ .

$\"\"$

The solution of the linear system is $\"\"$ .

Solution :

Graph the equations $\"\"$ and $\"\"$ .

$\"\"$

The solution of the linear system is $\"\"$ .
