1y-2(y-6)

y - 2y + 12

-y + 12

-y+12

To simplify the expression 1y-2(y-6), we follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Step 1: Simplify the expression inside the parentheses.
y-6

Step 2: Distribute the -2 to the terms inside the parentheses.
-2 * y = -2y
-2 * -6 = 12

Therefore, the expression becomes:
1y - 2y + 12

Step 3: Combine like terms.
(1 - 2)y + 12 = -y + 12

So, the simplified expression is -y + 12.

To simplify the expression 1y - 2(y - 6), follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right):

Step 1: Simplify inside the parentheses.
y - 6 remains as it is since no operations are applied.

Step 2: Distribute the -2 to the terms inside the parentheses.
-2(y - 6) = -2 * y + (-2) * (-6) = -2y + 12

Now we have:
1y - 2y + 12

Step 3: Combine like terms.
Combine the terms with a y:
(1y - 2y) + 12 = -1y + 12

The simplified expression is -1y + 12. However, we can also write it as 12 - y.
