Question

solve :2x+4<18, where x is a natural number​

Answer 1

Given - Expression containing variable to be found

Find - Variable X.

Solution - Solving the expression to find the value of X.

In the expression 2x + 4 < 18, taking 4 to the right hand side.

Now, 2x < 18 - 4

On solving we get, 2x < 14

Dividing the resultant expression by 2.

X < 7.

Thus, X can be any natural number ranging between 1 to 6.

Natural numbers are the numbers starting from 1 and continue till infinity.

Answer 2

SOLUTION

TO SOLVE

$\sf{2x + 4 < 18}$

Where x is a natural number

EVALUATION

Here the given inequality is

$\sf{2x + 4 < 18}$

We now solve for x

$\sf{2x + 4 < 18}$

$\sf{ \implies \: 2x < 18 - 4}$

$\sf{ \implies \: 2x < 14}$

$\sf{ \implies \: x < 7}$

Since x is a natural number

∴ x = 1 , 2 , 3 , 4 , 5 , 6

Hence the required solution set is

$\sf{S = \{ \: 1 , 2 , 3 , 4 , 5 , 6 \: \}}$
