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
