First add 1 to each side. It will leave you with an equation like this. 5x=3x -4
Next, subtract 3x from each side. It will leave you with an equation like this. 2x= -4
Lastly, divide each side by 2 so we can get x by itself.

Answer:
6 rolls
Step-by-step explanation:
Data provided in the question:
Height of wall = 9'
Width of walls = 13', 13', 18' and 18'
Dimension of roll = 3' x 2' x 50'
Now,
Total area of the walls = 9' × 13' + 9' × 13' + 9' × 18' + 9' × 18'
= 117 + 117 + 162 + 162
= 558 ft²
Area of each roll = 2' × 50'
= 100 ft²
Thus,
Number of rolls required = [ Total area of the walls ] ÷ [ Area of each roll ]
= 558 ft² ÷ 100 ft²
= 5.58 ≈ 6 rolls
