Step-by-step explanation:
Let the width=x
Length =6x-4
As we know that in a rectangle
- Substitute the values
- Here a=6, b=-4, c=-20.
- use quadratic formula
To solve this system by substitution, first isolate x in the second equation.
Now, plug this expression (
Now that you have y, plug it into the second equation and solve for x.
Last step is to plug your x- and y-values in to both equations to check your work.
