Answer:
∴ 85x - 24x² = 62
Explanation:
5x - (4x-7) (3x - 5) = 6-3 (4x -9) (x-1)
or, 5x - { 4x(3x -5) - 7(3x-5)} = 3 { 4x(x-1) - 9(x-1)}
or, 5x- ( 12x² - 20x - 21x+ 35) = 3 (4x² - 4x - 9x + 9}
or, 5x - (12x² -41x + 35) = 3 (4x² - 13x+9)
or, 5x - 12x² + 41x - 35 = 12x² - 39x + 27
or, 46x - 12x² -35 = 12x² - 39x +27
or, 46x + 39x - 12x² - 12x² - 35 - 27 = 0
or, 85x - 24x² - 62 = 0
∴ 85x - 24x² = 62
