Question

Problem 4: Simplify the expressions. Write your numerical answer. If youranswer has more than one term, write your answer in standard form and donot include space between the terms and the operation. 4-3(2 – x) + 5x

Answer 1

4-3(2-x) + 5x

first of all, we'll open the bracket

$\begin{gathered} 4-3(2-x)\text{ }+\text{ 5x} \\ multiply\text{ the bracket by 3 to open it} \\ 4\text{ }-\text{ 6 }+\text{ 3x }+\text{ 5x} \\ -2\text{ }+\text{ 8x} \end{gathered}$

step 1

apply BODMAS i.e Bracket Open Division Multiplication Addition and Subtraction.

so, according to BODMAS rule, open bracket comes first before subtraction so we

the answer is -2 + 8x
