Question

Solve 3m-18=6 by trial and error method

Answer 1

$\huge\mathbb\blue{Answer}$

3m-18=6

─────────────────────

➡let m=1

3(1)-18=6

3-18=6

-16=6

-16 is not equal to 6.

Therefore, 1 is not value of m.

─────────────────────

➡Let m be 2.

3(2)-18=6

6-18=6

-12=6

-12 is not equal to 6

Therefore, 2 is not equal to 2.

─────────────────────

➡Let m be 8.

3(8)-18=6

24-18=6

6=6

Therefore, m is equal to 8.
