The value x = -5 is a solution to the inequality 18x − 42 ≠ 7x.

What is inequality?

The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than, or < ‘less than.

For showing x =-5 is a solution of the inequality 18x − 42 ≠ 7x put x =-5 in the solution if it satisfies the condition then it is a solution of the given inequality.

18x − 42 ≠ 7x

18 x ( -5 ) - 42 ≠ 7 x ( -5 )

-132 ≠ -35

The value x = -5 is satisfying the given inequality. Hence, x = -5 is a solution to the inequality 18x − 42 ≠ 7x.
