Respuesta :

if it is 2(x+12=27*6-120

x is 9

if it is really

2x+12=27*6-120

x is 15

Hope that helps

Let's begin by solving the right side of the equation.  2(x+12)=27*6-120.  By the order of operations, PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction), 27*6 must happen first.  We can rewrite the equation as 2(x+12)=(27*6)-120.  27*6=162.  Let's continue.  2(x+12)=162-120.  162-120=42.  So, 2(x+12)=42.  Now, we have to isolate x.  Let's start by dividing out the 2 on BOTH sides of the equation, to use inverse operations: 2(x+12)/2=42/2.  x+12=21.  Finally, subtract 12 from both sides.  x+12-12=21-12.  x=9.

Answer: x=9
