Answer 2

$\sf{Solution:-}$

3 ( x + 7 ) = 18

We have to find value of x

3 ( x + 7) = 18

3x + 21 = 18

Tranpose 21 to RHS

3x = 18 - 21

3x = -3

x = -3 /3

x = - 1

Verification:-

Substuite value of x to get LHS=RHS

3 ( x + 7 ) = 18

At x = -1

3 ( - 1 + 7) = 18

3 (6) = 18

18 = 18

Verified !
