What does x equal when 21x plus 9 equals 180?
21x + 9 = 180 21x = 180 - 9 21x = 171 x = 171/21 x = 8.143
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.
What is the answer to 20x plus 5-20 equals 21x plus 4?
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
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 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
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.
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
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
Where does y equals 3x-5 and 21x-35 equals 7y intersect on a graph?
put both equations in standard form y - 3x = -5 (equation 1) -7y + 21x = 35 (equation 2) multiply equation 1 by 7 (this is done so either one of your variables will cancel... if both variables cancel then these lines are parallel) 7y - 21x = -35 -7y + 21x = 35 0 = 0 therefore your lines are parallel
What is the factored form of y equals 3x plus 21x squared?
y = 3x + 21x2 = 3x(1 + 7x)
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
What type of linear system is 7x plus 2y equals 16 -21x-6y equals 24?
Do you mean 7x+2y = 16 and 21x-6y = 24? If so then it is simultaneous equation with the solution being: x = 12/7 and y = 2
