Solve for x in simplest form 15 = 1/3(x+9)

x = 36

Step-by-step explanation:

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

Remember to follow PEMDAS and the left -> right rule.

15 = 1/3(x + 9)

First, multiply 3 to both sides of the equation

(15)(3) = (1/3(x + 9))(3)

(15)(3) = x + 9

45 = x + 9

Next, to isolate the x, subtract 9 from both sides

45 (-9) = x + 9 (-9)

45 - 9 = x

36 = x

36 is your answer for x.
