Solution for 2x plus y equals 5 and x-3y equals 13 by substitution?
2x + y = 5 so y = 5 - 2x; This gives x - 3(5 - 2x) = 13 ie x + 6x = 13 + 15 so x = 4 and y must be -3
Equation 2x plus 5 equals 25 for x?
2x + 5 = 25 2x = 20x = 10
What is the answer if 2 times a number plus three times a number equals 13?
if the number is the same: 2x + 3x = 13 5x = 13 x= 13/5
What is 6x plus 3 equals 2x plus 5?
6x + 3 = 2x + 5 4x = 2 x=1/2
If 4x minus 7 equals 2x plus 5 what is x?
4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.
What is 3x plus 5 equals 2x plus 13?
3x+5 = 2x+13 3x-2x = 13-5 x = 8
2x plus 5 equals 31?
2x + 5 = 31 2x = 31 - 5 = 26 x = 13
What is 4 plus 2x minus-2x plus 1 equals 13 plus 6?
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
2x plus 5 equals plus 13?
-2x+5=13 you subtract 5 away from +5 and this cancels out. you then do the same to the other side by taking 5 away from 13 therefor you get 8. Now you have -2x=8, take -2x and divide it into 8 and you get 4.
Find the value of x if 13 plus 2x equals 3?
13 + 2x = 32x = 3 - 132x = -10x = -5
Solution for 2x plus y equals 5 and x-3y equals 13 by substitution?
2x + y = 5 so y = 5 - 2x; This gives x - 3(5 - 2x) = 13 ie x + 6x = 13 + 15 so x = 4 and y must be -3
What is the vertex of the parabola y equals 2x squared plus 12x 13?
(-3, -5)
2x plus 5 equals 10x equals?
If your question was 2X + 5 =10. X equals what? Then X=2.5
2x plus 3y-5 plus -3y-6 equals?
2x-11
Solve x squared plus 2x - 13 equals 2?
(x - 3)(x + 5)
4x-3 equals 2x plus 5?
4x - 3 = 2x + 54x - 2x = 5 + 32x = 8x = 8/2x = 4To check:4(4) - 3 = 132(4) + 5 = 13
What is -3x plus -18 equals 2x plus 7?
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
