3(x-4) = x + 14
How do you solve this equation

x=13

Step-by-step explanation:

you have to isolate the variable

3(x-4)=x+14

distribute

3x-12=x+14

subtract 14 from each side

3x-26=x

subtract 3x from each side

-26=-2x

divide each side by -2

13=x

flip sides

x=13

hope this helps!!! :)

X= 8.6666

Step-by-step explanation:

First multiply ehat is on the outside by the inside.

3×X=3x

3×-4= -12.

Now you have 3X-12= X+14

First add -12 to 14.

Your goal is to get all the numbers on one side and the letters on the other side.

12+14=26.

Now you have 3X=26

To get the X by itself divide 3 on both sides.

X÷3= X

26÷3=8.6666

So your answer is X=8.6666

step-by-step explanation:

because there are always 10 numbers in a phone number.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
