Look at the system of equations.
 $y=-x+2$  
 $7x+4y=-1$  
What is the value of x for the solution to this system of equations?

Pierre solved an inequality as shown.

Step 1:   $-8\ge n+3$  
Step 2:   $-8+\left(-3\right)\ge n+3+\left(-3\right)$  
Step 3:   $-11\ge n+0$  
Step 4:   $-11\ge n$  

What property justifies the work between Step 3 and Step 4?

Which property of real numbers justifies the work shown?
 $13x-1=\left(12x+15\right)+7x$  
 $13x-1=7x+\left(12x+15\right)$
