Answer:

X = 8.3 (shortened)

Steps for answer!

1. Subtract 2.5x from both sides.

1.5=4x-11-2.5x

2. Simplify 4x-11-2.5 to 1.5x-11

1.5=1.5x-11

3. Add 11 to both sides.

1.5+11=1.5x

4. Simplify 1.5+11 to 12.5.

12.5=1.5x

5. Divide both sides by 1.5.

12.5/1.5=x

6. Simplify 12.5/1.5 to 8.3333338.333333.

8.333333=x

7. Switch sides.

x=8.333333

Hence the width is equal to 0.59255 cubic yards / (8/3)/(1/9) yards2 equal to 2 yards
