Asked by Dori
The teacher wants us to do the following problem by using substitution. I don't think I am doing it right.
4x - 12y =5
-x + 3y = -1
Those two equations are for parallel lines that never intersect. There is no solution.
If you substitute 3y +1 for x in the first equation, you will be led to an equation that cannot be valid, stating that two different constants are equal.
