Question

Which expression is equivalent to the given expression? (+2+6)-(- 2+3) x +9 O A I O B. - } +3 O C. x+3 OD. - *+9

Answer 1

The equivalent expression is;

`(5)/(7)x+3`

Step-by-step explanation:

We want to simplify the expression;

`((1)/(7)x+6)-(-(4)/(7)x+3)`

we will first multiply the negative by every term in the bracket, then simplify by collecting the like terms.

`\begin{gathered} (1)/(7)x+6-(-(4)/(7)x)-(+3) \\ (1)/(7)x+6+(4)/(7)x-3 \\ \text{collecting the like terms we have;} \\ (1)/(7)x+(4)/(7)x+6-3 \\ (5)/(7)x+3 \end{gathered}`

Therefore, the equivalent expression is;

`(5)/(7)x+3`
