Hello!
To find the value of x, you need to use SADMEP. SADMEP is PEMDAS reversed and it is only used when solving algebraic equations.
SADMEP is subtraction, addition, division, multiplication, exponents, and parentheses. SADMEP has the same rules as PEMDAS, you subtract, then add, after you divide, then multiply, etc.
The main goal when solving algebraic equations is to get the variable on one side the equation.
5 - 4x = -27 (subtract 5 from both sides)
-4x = -32 (divide both sides by -4)
x = 8
A good thing to always do is to check your work after solving equations. To check, you substitute the value of x back into the original equation and simplify. Since you are not solving algebraic equations, you need to use PEMDAS.
5 - 4x = -27; x = 8
5 - 4(8) = -27 (multiply)
5 - 32 = -27
-27 = -27 | This is correct!
Therefore, the answer is x = 8.
