Question

Which expression is equivalent to (11r – 8) + (7 4x)?

Answer 1

You need to determine which of the given options is equivalent to the expression

`(11x-8)+(7-4x)`

To determine the equivalent expression you have to simplify the equation.

-First, erase the parentheses and group the like terms together:

`\begin{gathered} 11x-8+7-4x \\ 11x-4x-8+7 \end{gathered}`

-Then, solve the operations between the like terms to simplify the expression:

`\begin{gathered} 11x-4x-8+7 \\ 7x-1 \end{gathered}`

The equivalent expression is 7x-1 (option C)
