Answer 2

Answer:

x = 7

Step-by-step explanation:

We have to solve the equation.

3x + 4 = 25

=> 3x = 25-4

=> 3×x = 21

=> x = 21÷3

=> x = 7

Hence the value of x = 7.

To verify (prove) :-

3x + 4 = 25

if x = 7

=> 3(7) + 4 = 25

=> (3×7) + 4 = 25

=> 21 + 4 = 25

=> 25 = 25

LHS = RHS

Hence it is verified that x = 7 is the solution of the equation.

hope it helps.
