ㅤ$\sf {\underline { ● \; According \; to \; Question :-}}$

• We need to check if 3 is the solution of the given equation or not .So,we will be checking it by substituting the value of 3 in the eq.

ㅤ

ㅤㅤㅤㅤㅤ$\implies{\boxed {\sf { x - 10 = -7}}}$

ㅤㅤㅤㅤㅤ

‎ㅤㅤㅤㅤㅤ$\implies{\boxed {\sf { 3 - 10 = -7}}}$

ㅤㅤㅤㅤㅤ

ㅤㅤㅤㅤㅤ$\implies {\boxed {\sf { -7=-7}}}$

ㅤㅤㅤㅤㅤ

ㅤㅤㅤㅤㅤ${\boxed {\sf {\red{ L.H.S = R.H.S}}}}$
