An algebraic expression
8x plus 4y equals 5 is 8x + 4y = 5.
5 + 8(3 + x) 5 + 24 + 8x 29 + 8x
7+8x-5 = 8x+7-5x Subtract 7 from both sides: 8x-5 = 8x-5x Subtract 8x from both sides: -5 = -5x Divide both sides by -5: x = 1 So the equation implies x = 1
x2+8x = -3x2+5 4x2+8x-5 = 0 (2x+5)(2x-1) = 0 x = -5/2 or x = 1/2
8x + 20 = 4 (2x + 5)
x2 + 8x + 15 = (x + 3)(x + 5)
x2 + 8x + 15 = (x + 3) (x + 5).
8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.
x3 + 2x2 - 8x + 5 = 0 x(2x - 8) + 5 = 0
x² + 8x + 15 = (x + 5)(x + 3)
(x + 1)(3x + 5)
5
