In order to solve for x, there must be an x in the equation.If you meant to say 3x/14=84, then 3x=14(84), so x=392 If you meant to say 3/14x=84, then 84x=3/14, so x=0.00255102041 If you meant to say 3/14=84x, then the above line is the answer.
21x+452 = 32-84x 21x+84x = 32-452 105x = -420 x = -4
x - 12 = 91 - 84x - 12 = 7x = 19
x = 2, y = 84x + 8y= 4(2) + 8(8)= 8 + 64= 72
49x2 - 84x + 36 = (7x - 6)(7x - 6) or (7x - 6)2
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
-82X, and you're missing an operator there.
x + (x + 1) + (x + 2) = 843x + 3 = 84x = 2727 + 28 + 29 = 84x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6)= 847x + 21 = 84x = 99 + 10 + 11 + 12 + 13 + 14 + 15 = 848x + 28 = 84x = 77 + 8 + 9 + 10 + 11 + 12 + 13 + 14 = 84

The answer to this can vary quite vastly. In equations, one is often finding the value of x or n. There are many ways to solve an equation and/or formula, so there is no direct answer to your question.Ex:4x = 5 + 34x = 84x / 4 = 8 / 4x = 2
It is a quadratic expression and it is (7x+6)(7x+6) when factored
Thanks to limitations of the browser used for posting questions, it is not possible to tell whether the sides are 6x - 7 units or 6x + 7 units. For 6x - 7 units, area = 36x2 - 84x + 49 square units. For 6x + 7 units, area = 36x2 + 84x + 49 square units.
