Exercise 14D
Question 1
Simplify:
1. $6 a-(5 a-2 x)$
2. $5 x+(3 x-7)$
3. $5 x+(-7 x-2 y)$
4. $3 y-(3 y+2)-6+(3 y-8)$
5. $4 x-[x-(4 x+3 y)+5 y]$
6. $-\{-2 b-(3 b+7 c)\}$
7. $4 x^{2}-\left[3 y^{2}-\left\{5 x^{2}-2 y^{2}-\left(x^{2}-y^{2}\right)\right\}\right]$
8. $2 a-3 b-[4 a-3 b-\{a-2 c-(a-2 b-c)\}$
Multiple Choice Question (MCQ)
Tick (✔) the correct option.
