-2(x+3)-5x
-2x - 6 - 5x
= -2x - 5x - 6
= -7x - 6
To simplify the expression -2(x + 3) - 5x, we can apply the distributive property by multiplying -2 to both terms inside the parentheses:
-2(x + 3) - 5x = -2x - 6 - 5x
Next, combine like terms by adding the coefficients of the x terms:
-2x - 6 - 5x = (-2x - 5x) - 6 = -7x - 6
Therefore, the simplified form of -2(x + 3) - 5x is -7x - 6.
To simplify the expression -2(x+3)-5x, we follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
First, let's simplify inside the parentheses. Distribute -2 to the terms inside the parentheses by multiplying each term inside by -2:
-2(x + 3) = -2 * x - 2 * 3 = -2x - 6
Now we can rewrite the original expression as:
-2x - 6 - 5x
Next, combine the like terms. In this case, we have two terms with x, so we can combine them:
-2x - 5x = -7x
Finally, we combine the constant terms:
-7x - 6
So, the simplified expression is -7x - 6.
