Question 1043938
.
Solve the system using the substitution method. If the system has no solution or an infinite number of solutions, state this.

x+y=7
6x+6y=42
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Divide the second equation by 6 (both sides),

and you will see that this equation become 

x + y = 7,

exactly as the first equation is.

So, you have here the system of two equivalent (depending) equations.


The system has infinitely many solutions.
