Question

solve the following equations?? ​

Answer 1

Answer:

2nd ans-4

Step-by-step explanation:

7(x-1)=21

7x-7=21

7x=21+7

x=28/7

x=4

Answer 2

Answer:

Step-by-step explanation:

a) 11x-5-x+6 = 2x+17

    Adding or subtracting the like terms

   10x+1 = 2x+17

   Transposing 2x to LHS and 1 to RHS

   10x-2x = 17-1

    8x = 16

    x = 16/8

    x = 2

b) 7(x-1)=21

   Transposing 7 to RHS

   x-1 = 21/7

   Transposing 1 to RHS

   x-1 = 3

    x = 3+1

    x = 4

Hope it helps,

Have a good evening.
