EG = 72. If EF = 4x+ 3 and FG = 6x + 9, then x = ?

6 is your answer for x.

Step-by-step explanation:

EG = 72

F is the midpoint of EG.

Set the equation:

EG = EF + FG

Plug in the corresponding terms to the corresponding variables:

72 = (4x + 3) + (6x + 9)

Combine like terms (terms with the same amount of variables):

72 = (4x + 6x) + (3 + 9)

72 = (10x) + (12)

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and =

First, subtract 12 from both sides:

72 = 10x + 12

72 (-12) = 10x + 12 (-12)

72 - 12 = 10x

60 = 10x

Divide 10 from both sides:

(60)/10 = (10x)/10

x = 60/10

x = 6

x = 6 is your answer.
