7x=266

X=266/7

x=38

Q. No. 2

Let the number be x

15+3x=93

3x=93-15

3x=78

x=78/3

x=26

Q.no.3

5x-3(2x+1)=21+x

5x-6x-3=21+x

5x-6x-x=21+3

-2x=24

X=24/-2

X=-12

Q.no 4

3x-4and2x+1

3*5-4and2*5+1

15-4and10+1

11and11

Value of x will be 5

Q.no 5

3x-256+4x=10

7x=10+256=266

x=38

2.let the whole no is x then

3x+15=93

3x=78

x=26 which is required whole no

3. 5x-3(2x+1)=21+x

collecting x one side u get

-2x=24

x=-12

4.: 3x-4=2x+1

3x-2x=5

x=5
