Bro I really need this answer (I’ll mark brainliest)

Given:

Point G is the centroid of triangle ABC.

FG = x + 8 and AG = 6x - 4

To find:

The value of the variable x.

Solution:

Using  rule of centroid:

Multiply by 3 on both sides, we get

⇒ 3(6x - 4) = 2(7x + 4)

⇒ 18x - 12 = 14x + 8

Subtract 14x from both sides.

⇒ 4x - 12 = 8

Add 12 on both sides.

⇒ 4x = 20

Divide by 4 on both sides.

⇒ x = 5

The value of x is 5.

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
