8 was subtracted from a number. Then, that difference was multiplied by 2, after which that result was divided by 11. If the result was negative 2 what was the initial number

-3

Step-by-step explanation:

Let's call the initial number by 'x'.

First we have x - 8

Then, we have 2*(x-8)

Then, we have 2*(x-8)/11

And this result is equal to -2

So, we need to solve the equation 2*(x-8)/11 = -2

2*(x-8)/11 = -2

(x-8)/11 = -1

(x-8) = -11

x = -3

The inicial number is -3

step-by-step explanation:

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
