First step is to combine like terms. 

9 = 7x - 13x - 21 becomes 9 = - 6x - 21

Now add 21 to both sides to isolate our coefficient and variable. 

- 6x -21 + 21 = 9 + 21

The 21s on the left cancel out. 

- 6x = 30

Now divide both sides by - 6 to isolate the variable. 
x = 30 / - 6
x = - 5

Use Pythagorean theory
Split square into two right triangles with diagonal line. To find the diagonal

162= c^2
Take square root of both sides
12.73 = c
