Answer:

  -2

Step-by-step explanation:

We assume you want to find the number. Let it be represented by x.

  (6+2x)·5 = -3x +4 . . . . . the meaning of the problem statement

  30 +10x = -3x +4 . . . . . eliminate parentheses

  26 +13x = 0 . . . . . . . . . add 3x-4 to both sides

  2 + x = 0 . . . . . . . . . . . . divide by 13

  x = -2 . . . . . . . . . . . . . . subtract 2

The number is -2.

Which of the graphs below represents the equation 8x - y = -4?
vichka [17]
Well since you dont have the graphs posted i can tell u the y-intercept and the slope and you can figure it out from there.

8x-y=-4
-y=-8x-4
y=8x+4
the y intercept is 4 and the slope is positive 8
