3m-19=14
what it be???

m=11

Step-by-step explanation:

Add 19 to both sides.

3m−19+19=14+19

3m=33

Divide both sides by 3.

3m/3=33/3

m=11

m=11

Step-by-step explanation:

We want to isolate m on the left side of the equation.

3m-19=14; add 19 to both sides, now you have:

3m=33; divide 33 by 3:

m=11

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
