How can i simplify

We will use PEMDAS rule to simplify the given expression.

PEMDAS rule is given by:

P
-Parentheses first

E
-Exponents (ie Powers and Square Roots, etc.)

MD-Multiplication and Division (left-to-right)

AS
-Addition and Subtraction (left-to-right)

Step 1: P-parenthesis first.

(3-9) is -6

√16 -1 = 4-1 =3

So new expression becomes :

Step 2:

Multiplying (-3)*(-6)*2

We get +36

So new expression becomes : 25 +36

Step 3: Addition

Adding 25 and 36 we get 61

So final answer is 61 .

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
