Question

A rectangle has a length of 28 feet less than 6 times its width. if the area of the rectangle is 98 square feet, find the length of the rectangle.​

Answer 1

w = 18 is the solution

The equation for this problem is 6w - 28 + w = 98

w stands for width

Explanation:

7x - 28 = 98 Collect like terms

7w = 98 +28 Move the constant to the right hand side and change its sign

7w = 126 Add the numbers

w = 18 Divide both sides of the equation by 7
