literally, make an equation:
20.6 + 2.1x = -8.2x
left has two terms. you want to simplify the terms given in the equation.
Move -8.2x to left, (change sign of the term) or:
20.6 + 2.1x -2.1x = -8.2x -2.1x
20.6 = -10.3x
both sides need to be divided by -10.3 to solve for x:
20.6/(-10.3) = -10.3x /(-10.3)
-2 = x
You solved for x : x= -2

What does x equal when 21x plus 9 equals 180?
21x + 9 = 180 21x = 180 - 9 21x = 171 x = 171/21 x = 8.143
What is the answer to 20x plus 5-20 equals 21x plus 4?
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
How do you solve for x in 21x plus 2?
Your question is incomplete. 21x + 2 = [?] Whatever one does to one side they must do to the other so even if you divided by X you would have: 23 = ?/X
How do you solve 21x-7y equals 4?
You plot the equation as a graph. Every one of the infinitely many points on the graph is a solution.
How does y equals 4x2 plus 21x look in a graph?
It is a parabola with its vertex at the origin and the arms going upwards.
What is 21x equals 6x plus 30?
234 it is not the answer
What does x equal when 21x plus 9 equals 180?
21x + 9 = 180 21x = 180 - 9 21x = 171 x = 171/21 x = 8.143
2x square plus 21x plus 49?
i hope you mean (2x^2 + 21x + 49) you cant solve it its already in its lowest possible form
What is the answer to 21x plus 452 equals 32-84x?
21x+452 = 32-84x 21x+84x = 32-452 105x = -420 x = -4
What is the answer to 20x plus 5-20 equals 21x plus 4?
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
What answer 21x plus 12x - 2 equals?
21x + 12x -2 = 0 33x -2 = 0 33x = 2 x = 2/33 x = 0.06

It is a parabola with its vertex at the origin and the arms going upwards.
7x plus 7 equals 28 x equals?
7x+7=28x 28x-7x=7 21x=7 x=3
Is 7x plus 2y equals 16 and -21x-6y equals 24 a no solution?
Multiplying the first equation by -3 gives -21x - 6y = -48 but the other equation gives 24 as the value of the same expression, so you are correct, there is no solution
What is the answer 21x plus 12x - 2 equals?
I'm assuming that your solving for X. 21x + 12x - 2 = 0 33x - 2 = 0 33x = 2 x = 2/33 x =.06
