Can anyone solve this equation 8x-19= -4-7x

Step-by-step explanation:

consider that (x,y) is a general point on the line (variable), and (x1, y1) is a given fixed point on the line  

M, the slope of the line may be given as:  

M = (y - y1) / (x - x1)  

if you know the value of M, and the values x1 and y1, (which you do, since point (x1, y1) is given to you as a fixed point),  

you can rearrange the above equation to get the equation of the line  

the reason for this is that every point (x,y) on the required line will satisfy the above equation ( (x,y) is a general point )  

which means this equation is a relation between x and y which gives us the values of x and y which make (x,y) fall on the line  

this means that the obtained relation is nothing but a representation of the required line, ie equation of the line  

in the second example, fixed point is (x1, y1) =(1, 0)  

M = (-4)  

x1 = 1  

y1 = 0  

we have,  

M = (y - y1) / (x - x1)  

ie (-4) = (y - 0) / (x - 1)  

ie (-4) = y / (x-1)  

ie y = -4x + 4  

ie [ 4x + y = 4 ]  

which is the equation of the line  

the first example is almost the same thing  

onlhy in this case you have to find the slope M manually  

M = (y2 - y1) / (x2 - x1)  

where (x1, y1) and (x2, y2) are given fixed points on the line  

in the example,  

M = [ 5 - (-3) ] / [ 3 - 2 ]  

M = 8 / 1  

M = 8  

and proceed in a manner similar to the other example

x = 1

Step-by-step explanation:

8x - 19 = -4 - 7x

Combine x's on one side of the equation and constants on the other side.

8x + 7x = -4 + 19

15x = 15

Divide both sides by 15

x = 1

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
