Can you post a picture please!
<span>This means the length of the side of an area, a rectangle, for example, is always the same.
Hope this helps!</span>
Step-by-step explanation:
Simplify the left side:
5x - 20 = 3x + 4
Move all terms containing x to the left side of the equation:
2x - 20 = 4
Move all terms not containing x to the right side of the equation:
2x = 24
Divide each term by 2 and simplify:
x = 12
