Answer:
Step-by-step explanation:
To solve this problem, first you have to isolate it on one side of the equation. Remember to solve this problem, addition property of equality is adding from both sides of an equation the same number doesn't change the equation.
First, rewrite the problem down.
c+9=16
Next, subtract 9 from both sides.
c+9-9=16-9
Solve.
16-9=7
Therefore, the correct answer is c=7.

Step-by-step explanation:
Given the width is of the length, then
y - 4 = (2y + 6)
Multiply through by 3 to clear the fraction
3y - 12 = 2y + 6 ( subtract 2y from both sides )
y - 12 = 6 ( add 12 to both sides )
y = 18
Thus
length = 2y + 6 = 2(18) + 6 = 36 + 6 = 42 in
width = y - 4 = 18 - 4 = 14 in
