Answer 2

Given equation:

3(m+2) - 9 = 15

________________________________

Solution:

$\implies \sf {3(m+2) - 9 = 15}$

$\implies \sf {3m+6 - 9 = 15}$

$\implies \sf {3m-3 = 15}$

$\implies \sf {3m = 15+3}$

$\implies \sf {3m = 18}$

$\implies \sf {m = \dfrac {18}{3}}$

$\implies {\boxed {\bf {\red {m=6}}}}$

________________________________

Verification:

☆ Substitute the value of m as 6 in the equation,

$\implies \sf {3(m+2) - 9 = 15}$

$\implies \sf {3(6+2) - 9 = 15}$

$\implies \sf {3 \times 8 - 9 = 15}$

$\implies \sf {24- 9 = 15}$

$\implies \sf {24- 9 = 15}$

$\implies \sf {15 = 15}$

$\bigstar \sf {LHS = RHS}$

$\bigstar \sf {Hence\ Verified!}$

Value of m:

The value of m is 6.
