Question

Solve for $a$: $(a+4)+(a-2)=2$

• A. -14
• B. 8
• C. 14
• D. 0

Answer 1

The correct option is D

0

Given $(a+4)+(a-2)=2$

$=a+4+a-2=2$ [Removing brackets]
[rearranging the terms]
$a+a+4-2=2$
$2a+2=2$
$2a=2-2$ [when +2 is transposed to RHS it becomes -2]
$\Rightarrow 2a=0$
[dividing each term by 2]
$\Rightarrow a=\frac{0}{2}=0$
