X(x - 2) = 4 [upon multiplying and moving the 4 becomes x² - 2x - 4 = 0] x(2x + 3) = 12 [upon multiplying and moving the 12 becomes 2x² - 3x - 12 = 0] 3x(x + 8) = -2 [upon multiplying and moving the -2 becomes 3x² + 24x + 2 = 0]
Answer:
4
Step-by-step explanation:
(10 - x ) / x = 3/2 Cross Multiply
2*(10 - x) = 3x Remove the brackets
20 - 2x = 3x Add 2x to both sides
20 = 3x + 2x
5x = 20 Divide both sides by 5
x = 20/5
x = 4
