5x - 9 = 4x 5x - 4x - 9 = 4x - 4x x - 9 = 0 x - 9 + 9 = 0 + 9 x = 9
(2x - 3)(4x + 9)(2x + 3) = (2x - 3)(2x + 3)(4x + 9) = [(2x)^2 - (3^2)](4x + 9) = (4x^2 - 9)(4x + 9) = (4x^2)(4x) + (4x^2)(9) - (9)(4x) - (9)(9) = 16x^3 + 36 x^2 - 36x - 81
4x+5 = -9 4x = -9-5 4x = -14 x = -3.5
4x - 9 = 35 4x = 35 + 9 4x = 44 4x/4 = 44/4 x=11
4x+9=25 4x+9=25-9 4x/4=1 16/4=4 4x+9=26 4(4)+9=25 16+9=25 The answer is 4
4X - 1 = 9 Is an equation. 4X - 1 = 9 4X = 10 X = 5/2 =====
3y = 4x + 9 -4x + 3y = 9 is the standard form
As there are no parentheses then the expression stated can be simplified as follows :- 7x - 4x - 9 = 3x - 9 If the parentheses were placed (7x - 4x) - 9 then the result would be the same. If the parentheses were placed 7x - (4x - 9) = 7x - 4x + 9 = 3x + 9.
5x = 4x + 9 x = 9
4x + 32x + 9 = 36x + 9
2*2+4x-9=0 4x=9-4 4x=5 x=5/4
If the question gives 4x-3=9, then we can solve: 4x-3=9 4x=6 x=3/2, or 1.5
