Hey!
so first distribute the 5 to x + 4
5x+20 = 2x + 20 + 2x
combine 2x and 2x
5x+20 = 4x + 20
Now you want the constant and variable on different sides so subtract 4x to the other side
5x - 4x + 20 = 20
1x + 20 = 20
now subtract the 20 on the 1x + 20 side to the other side
1x = 0
divide by 1
0 divided by anything is 0
So x = 0
Hope this helps!

I saw the image that should accompany the above problem.
Courtyard: Length=22 ft; Width = 12 ft
Fountain: Length = 6 ft; Width = ?
Area of the courtyard = 22 ft * 12 ft = 264 square feet
Part of the courtyard covered with stone has an area of 246 square feet.
Area of the fountain = 264 square feet - 246 feet = 18 square feet.
A) Width of the fountain.
Area of the fountain = Length * width
18 square feet = 6 ft * w
18 sq.ft / 6ft = w
3 ft = width
B.) Fraction of the area of the courtyard will be occupied by the fountain.
Area of the fountain: 18 square feet
Area of the courtyard: 264 square feet
18/264 = 3/44
18 ÷ 6 = 3
264 ÷ 6 = 44
