Therefore, the next step is substitute these values into , then you get:
You can observe that this matches with the last option.
Problem 3
<h3>Camille is correct</h3>You subtract 4x from both sides, then divide both sides by -2 to fully isolate y.
===============================================
Problem 4
Multiply both sides by r to get
2mr = p-q
which is the same as
p-q = 2mr
The last step is to add q to both sides leading to this final answer
<h3>p = 2mr+q</h3>================================================
