-9y+[7+(6y-7)]
what is the algebraic expression in simplest form?
It is either a typo or the brackets are unnecessary
-9 y + 7 + 6 y - 7 = -3 y
-9y+[7+(6y-7)]
-9y+[7+6y-7]
-9y+7+6y-7 = -3y.
To simplify the algebraic expression -9y+[7+(6y-7)], we will follow the order of operations (also known as PEMDAS: Parentheses, Exponents, Multiplication and Division - from left to right, Addition and Subtraction - from left to right):
First, let's simplify the expression within the inner parentheses - (6y-7):
-9y + [7 + 6y - 7]
Next, combine like terms within the inner parentheses:
-9y + [6y]
Now, simplify the expression within the outer parentheses - [6y]:
-9y + 6y
Lastly, combine like terms:
-3y
Therefore, the simplified form of the algebraic expression -9y + [7 + (6y - 7)] is -3y.
