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
24x^3-40x^2. 45x-75
8x^2(3x-5). 15(3x-5)
(8x^2+15)(3x-5)
Answer:
12 I think I counted it hope it's correct
