Question

x=3 is the solution of the equation 3x+5=12-x . Is it true or false ​

Answer 1

Step-by-step explanation:

Correct option is true

Given, 13=3x−2

Add 2 on both the sides we get,

13+2=3x−2+2

15=3x

Divide both sides by 3 we get,

3

15

=

3

3x

∴x=5

Hence, the given statement is True

Answer 2

Answer:

The value of unknown variable which satisfies the equation is called solution of the equation.

So, substituting

x=3

we get

3+3 i.e. 6

which is not equal to zero. So, 3

is not the solution of the equation
