5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
If: 3x+7 = -14 Then: x = -7

(3x-2)(2x+7) is the same as 6x^2 +17x -14 when the brackets are multiplied out
X>-14
5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
-2X ? 14- 3x - 7 I am assuming you left something out so I put the question mark in. If it is -2X + 14 - 3x - 7 -Combine like terms -2x - 3x + 14 - 7 -5x + 7 DONE If it is -2X - 14 - 3x - 7 -Combine like terms -2X - 3X - 14 - 7 -5X - 21 DONE
If: 3x+7 = -14 Then: x = -7
13x-14 or 13x+(-14)

(3x-2)(2x+7) is the same as 6x^2 +17x -14 when the brackets are multiplied out
3x2 - 19x - 14 = 0 3x2 - 21x + 2x - 14 = 0 3x(x - 7) + 2(x - 7) = 0 (x - 7)(3x + 2) = 0 x - 7 = 0 or 3x + 2 = 0 x = 7 or x = -2/3
14
X>-14
(3x-2)(2x+7) is the same as 6x^2 +17x -14 when the brackets are multiplied out
(3x-2)(2x+7) is the same as 6x^2 +17x -14 when the brackets are multiplied out
3x + 7y = 14Subtract 3x from each side:7y = -3x + 14Divide each side by 7:y = -3/7 x + 2
