X plus 20 plus 10x equals 20 plus 9x x equals?
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0
What does 20 divided by 4 times 2 plus 6 equal?
20 divided by 4 multiplied by 2 plus 6 equals 16. 20/4 = 5, 5x2 = 10, 10+6 = 16.
5x plus 2 for x equals 4?
If X = 4 then 5X is equal to 5 x 4 which is 20. So 20 + 2 = 22.
What are the solutions to the simultaneous equations of 2x -3y equals 4 and 5x plus 2y equals 1?
Equations: 2x-3y = 4 and 5x+2y = 1 Multiply all terms in 1st equation by 5 and all terms in 2nd equation by 2:- So: 10x-15y = 20 and 10x+4y = 2 Subtract the 2nd equation from the 1st equation: -19y = 18 => y = -18/19 By substitution the solutions are: x = 11/19 and y = -18/19
Solve 4y equals 2y plus 40?
4y = 2y + 40 4y - 2y = 2y -2y +40 2y = 40 y = 20 check 4(20) = 2(20) +40 80 = 80
What is x in the problem 2x plus 10x - 4 equals 20?
2x + (10x - 4) = 20 2x + 10x - 4 = 20 12x - 4 = 20 12x = 24 x = 2
X plus 20 plus 10x equals 20 plus 9x x equals?
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0
0 equals 800-10x plus 25x2?
If you mean:0 = 800 - 10x + 25 * 20 = 800-10x+25*210x = 800+50x = 8,50 = 800 - 10x + 25 * x * 20 = 800 - 10x + 50x-800 = 40x-50 = x
How do you find the value of the discriminant -16x2 plus 10x-20 equals 0?
Calculate 10^2 - 4*(-16)*(-20)
What is 12x-3 equals 2x plus 17 algebra?
12x-3=2x+17 10x-3=17 10x=20 x=2
10x-18 equals 5x plus 2?
10x - 18 = 5x + 2 Add -5x + 18 to both sides of the equation, to get: 5x = 20, from which x = 4.
98 subtract 3x equals 10x plus 20?
98 - 3x = 10x + 20, solve for x.subtract 98 from both sides-3x = 10x - 78subtract 10x from both sides-13x = -78multiply both sides by -113 x = 78divide both sides by 13x = 6
What is the answer to -20 equals -4x -6x?
-20 = -4x - 6x -20 = -10x -20 / -10 = -10x / -10 2 = x x = 2
What is the answer to 10x-15x plus 5-45 plus 20?
It is: -5x-20 when simplified
4X-12 plus 6X equals 8?
Add 12 to each side: 4x + 6x = 20 ie 10x = 20 so x = 2
What is x plus 20 plus 10x plus 9x?
The given terms can be simplified to: 20x+20
