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.

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.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
