This form needed. Y = mX + c
2X + 8Y = 40
8Y = - 2X + 40
Y = - 1/4 + 5
-----------------------zero out the Y
- 1/4X + 5 = 0
- 1/4X = - 5
X = 20
-------------------your X intercept

2x plus 3y equals 40 and -2x plus 2y equals 20?
Add the two equations you get 5y = 60 so y = 12 and x = 2
If 2x plus 2x equals 40 what does x equal?
To solve for x, set up the equation: 2x +2x = 40 (then simplify) 4x = 40 (then divide both sides of the equation by 4) x = 10 (this is the answer)
Solve by the method of elimination 2x plus 3y equals 40 3x plus 2y equals 20?
y=16 x= -4
2x plus 9 equals 49 -3x?
2x+9 = 49-3x 2x+3x = 49-9 5x = 40 x = 8
What is the answer to 8x-40 equals 2x plus 2?
7. 8x-40=2x+2 4x-20=1x+1 3x-21=0 3x=21 therefore x=7
3x plus 2x equals 40?
3x + 2x = 40 5x = 40 x = 8
2x plus 3y equals 40 and -2x plus 2y equals 20?
Add the two equations you get 5y = 60 so y = 12 and x = 2
10-3x equals x-2x plus 40?
10 - 3x = x - 2x + 40 10 - 3x = - x + 40 10 - 40 = 3x - x -30 = 2x -15 = x
If 2x plus 2x equals 40 what does x equal?
To solve for x, set up the equation: 2x +2x = 40 (then simplify) 4x = 40 (then divide both sides of the equation by 4) x = 10 (this is the answer)
Solve by the method of elimination 2x plus 3y equals 40 3x plus 2y equals 20?
y=16 x= -4
2x plus 9 equals 49 -3x?
2x+9 = 49-3x 2x+3x = 49-9 5x = 40 x = 8
What is the value of x in the equation 2x plus 17 equals 6x-23?
2x+17=6x-23 23+17=6x-2x 40=4x x=40 / 4 therefore x=10
6x-52 equals 4x plus 40?
6x-52 = 4x+40 6x-4x = 40+52 2x = 92 Answer: x = 46
What is the answer to 8x-40 equals 2x plus 2?
7. 8x-40=2x+2 4x-20=1x+1 3x-21=0 3x=21 therefore x=7
What is the answer to 2x equals 40?
x=20
What is the answer to 2x squared -2x -40 equals 0 is it x equals 5 and x equals -4?
Yes it is and well done.
X squared plus 2x plus 40 equals x squared-x plus 190 what is the value of x?
x^2+2x+40 = x^2-x+190Subtract x^2 from both sides2x+40 = -x+190Add x to both sides3x + 40 = 190Subtract 40 from each side3x = 150Divide both sides by 3x = 50
