1. $8 + (a-2)$ 2. $5+ (a-2)$
Given :
The given expressions are 1. $8 + (a-2)$ 2. $5+ (a-2)$
To do :
We have to simplify the given expressions
Solution :
1. $8 + (a -2) = 8 + a -2$
Regrouping 'Like Terms' 8 and $-2 = 8-2 + a = 6 + a$
2. $ 5 + 2(a-2) = 5 + 2a +2\times(-2) = 5 + 2a -4$
Regrouping 'Like Terms' $= 5-4 + 2a = 1 + 2a$
The simplified value of $8 + (a -2)$ is $6 + a$
The simplified value of $ 5 + 2(a-2)$ is $1 + 2a$
