6x+1-x-3 = 8x-5-8 5x-2 = 8x-13 5x-8x = -13+2 -3x = -11 x = 11/3
x^2-8x+3 = x^2-8x+16-16+3 = (x-4)^2-13 y=(x-4)^2 -13 The vertex is (4,-13).
5x + 4 - 8x = 13 5x + 4 + -8x = 13 (Put the x variables together) 5x + -8x = -3x -3x + 4 = 13 | -4 | -4 (Subtract 4 from both sides) -3x = 9 (Divide both sides by -3 to get the 'x' by itself) ---- --- -3 -3 x = -3
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
When simplified it is: 1-8x
6x+1-x-3 = 8x-5-8 5x-2 = 8x-13 5x-8x = -13+2 -3x = -11 x = 11/3
x^2-8x+3 = x^2-8x+16-16+3 = (x-4)^2-13 y=(x-4)^2 -13 The vertex is (4,-13).
4x+8x+3 = 12x+3
(8x + 3)2 ie (8x + 3)(8x + 3)
5x + 4 - 8x = 13 5x + 4 + -8x = 13 (Put the x variables together) 5x + -8x = -3x -3x + 4 = 13 | -4 | -4 (Subtract 4 from both sides) -3x = 9 (Divide both sides by -3 to get the 'x' by itself) ---- --- -3 -3 x = -3
16x + 3
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
When simplified it is: 1-8x
-8x + 3 = 27 -8x = 27 - 3 -8x = 24 -x = 3 x = -3
2X + 6X - 3 = 13 add 2X and 6X together 8X - 3 = 13 add 3 to each side 8X - 3 + 3 = 13 + 3 8X = 16 divide both sides integers by 8 (8/8)X = 16/8 X = 2 ----------------check in original equation 2(2) + 6(2) - 3 = 13 4 + 12 - 3 = 13 13 = 13 checks
-8x + 3x2 - 3
6x plus 3 equals to 8x plus 14 would lead to x = - 5.5.
