Answer: Length= 2x-3
(X=width)
Step-by-step explanation:
If the length is 3 less than 2 times the width, that means you're really just subtracting 3 from double the width. Since the width is unknown, we use the variable X. 2 times the width would be 2x because x is the stand in for width since it's an unknown number. Therefore, 2x-3.
