Question

The value of x + 7 + 4(x – 5) for x=2



2. The value of expression 2a – 2b – 4 – 5 + a at a=1, b=-2

3. What must be subtracted from 2a + b to get 2a – b

4. What must be added to 3x + y to get 2x + 3y



5. Subtract a + 2b from sum of a – b and 2a+b

6. On simplifying (a + b – 3) – (b – a +3) + (a – b + 3) the result is



7. What should be value of ‘a’ if y
