     What is happening from step 1 to step 2?    

            -3(1 + 2r) = 13 - 6r

Step 1     - 3 + 2r = 13 - 6r

Step 2       -3 + 8r = 13

Step 3           8r = 16

Step 4             r = 2

from step 1 to 2 

- the 6r is being brought to the left side through addition

What is happening from step 2 to step 3?    

            -3(1 + 2r) = 13 - 6r

Step 1     - 3 + 2r = 13 - 6r

Step 2       -3 + 8r = 13

Step 3           8r = 16

Step 4             r = 2

If my equation has the same variable/unknown on BOTH sides of the equal sign - what is the first thing I should do to try to solve it?

6x + 12 = 4x - 7

Isolate x to one side, combine like terms

if the value for (m) is a negative number, does the line for the equation go right or left?

Left

What is happening from step 3 to step 4?    

            -3(1 + 2r) = 13 - 6r

Step 1     - 3 + 2r = 13 - 6r

Step 2       -3 + 8r = 13

Step 3           8r = 16

Step 4             r = 2

Getting 8 away from r, diving both sides by 8 


16/8 = 2

Which step was done incorrectly and why?    

            -3(1 + 2r) = 13 - 6r

Step 1     - 3 + 2r = 13 - 6r

Step 2       -3 + 8r = 13

Step 3           8r = 16

Step 4             r = 2

step 1, the distributive property was done incorrectly 

they forgot to distribute -3 to 2r

A line contains the points (4,2) and (0,-1). What is the equations of the line?

y = 3/4x - 1

500

This problem is incorrect, how can you tell? Where is the mistake?    

            -4(1 + 3r) = 6 - 6r

Step 1     - 4 - 12r = 6 - 6r

Step 2       - 12r  = 10 - 6r

Step 3           - 18r = 10

Step 4              r = - 10/18

Step 2 to 3, -6 is subtracted both sides but needed to be added to both sides

- 6r = 10

r = -6/10

r = - 3/5
