Answer 1

Answer :–

• The correct option is (A) 18.

Given :–

• A linear equation, 3x – 2x = 18

To Find :–

• Value of x.

Solution :–

So, the given equation is,

⟹ 3x – 2x = 18

Now, subtract L.H.S. numbers.

⟹ 1x = 18

We can also write as,

⟹ x = 18

Hence,

The value of x is 18.

So, the correct option is (A) 18.

Check :–

Given linear equation,

⟹ 3x – 2x = 18

• x = 18

Now, put the value of x in the given linear equation.

⟹ 3(18) – 2(18) = 18

Now, Open both the brackets.

⟹ 54 – 36 = 18

Now, Subtract both the numbers.

⟹ 18 = 18

Since, the L.H.S. and the R.H.S. are equal.

So, the option (A) is correct.

Answer 2

x=18
EXPLANATION:
3x-2x=18
1x=18
x=18
