To Find:

Value of :

a) x + 10

b) x - 7

Solution:

Substituting value of x in given equations we will get the answers:

a) x + 10

2 + 10

= 12

$\sf\therefore$ value of x + 10 = 12.

b) x - 7

2 - 7

= - 5

$\sf\therefore$ value of x - 7 = - 5.

Verification:

a) we got x + 10 = 12

x + 10 = 12

x = 12 - 10

x = 2.

we got the given value that x = 2

Hence , verified.

b) we got x - 7 = - 5

x - 7 = - 5

x = - 5 + 7

x = 2

we got the given value that x = 2

Hence , verified.
