Question

check whether the linear equation 3x + 5=11
x= 2 is true

Answer 1

Answer:

yes

Step-by-step explanation:

f(x)= 3x +5 =11

L.H.S

f(2)= 3(2) + 5

=6+5

=11

L.H.S = R.H.S

Answer 2

Yes the linear equation 3x + 5 = 11 is true for x = 2

Given :

The linear equation 3x + 5 = 11

To find :

Check whether the linear equation 3x + 5 = 11 is true for x = 2.

Solution :

Step 1 of 2 :

Write down the given linear equation

Here the given linear equation is

3x + 5 = 11

Step 2 of 2 :

Check whether the linear equation 3x + 5 = 11 is true for x = 2.

The linear equation is

3x + 5 = 11

For x = 2 we get

LHS = ( 3 × 2 ) + 5 = 6 + 5 = 11

RHS = 11

∴ LHS = RHS

Hence , Yes the linear equation 3x + 5 = 11 is true for x = 2
