In 50-3x=8 why do we write -3 after subtracting both the sides with 50 while solving ​

see below

Step-by-step explanation:

50-3x=8

The first step is subtract 50 from each side

50-50-3x=8-50

-3x = -42

Then divide each side by -3

-3x/-3 = -42/-3

x = 14

Because -3x is remain after eliminate 50 on both sides.

Step-by-step explanation:

I. Solve 50 - 3x = 8

            50 - 3x = 8

   -50  +50 - 3x = 8 - 50 => {when 50 is +50}

                  -3x = -42 => {when -50 + 50 = 0 and -3x = -3x}

                      x = (-42)/(-3)

                      x = 14

Hope that help :)

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

the answer is 489
