... The ordered pair that is the point of intersection represents the solution that satisfies BOTH equations. If two lines are parallel to each other, then there is no solution. The lines will never intersect. If two lines lay one on top of another then there are infinite solutions. Every point on the l ...

Solve linear systems by substitution.
... makes the substitution method easier. Step 2: Substitute for that variable in the other equation. The result should be an equation with just one variable. Step 3: Solve the equation from Step 2. Step 4: Substitute the result from Step 3 into the equation from Step 1 to find the value of the other va ...
