Question

Simplify the following expression. (3 + 8 x ) + 7 x 3 + 15x 18 x 18 + x11 x + 7

Answer 1

Given the expression;

(3+8x)+7x

First thing we need to do is open up the parenthesis as shown;

`\begin{gathered} =(3+8x)+7x \\ =\text{ 3+8x+7x} \end{gathered}`

Simplify by adding up the like terms as shown;

`\begin{gathered} =\text{ 3 + 8x + 7x} \\ =\text{ 3 + 15x} \end{gathered}`

Hence option A is correct
