This is very important!!
an equation is shown below: 8x + 2(x – 7) = 7x + 3x – 14
part a: solve the equation and write the number of solutions. show all the steps. (6 points)
part b: name one property you used to solve this equation. (4 points)

 2.1      Pull out     10x-14 

After pulling out, we are left with :  
      (10x-14) • ( 1 +( (-1) ))

 3.1     Pull out like factors :

   10x - 14  =   2 • (5x - 7) 

8x + 2(x – 7) = 7x + 3x – 14

Part A: Solve the equation and write the number of solutions. Show all the steps. (6 points)

Part B: Name one property you used to solve this equation. (4 points)

Step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

is there a graph
