Answer:

\Large{\bf{\purple{\mathfrak{\dag{\underline{\underline{Question :}}}}}}} \:†

Question:

Solve :

→ 2(x+3) = x + 7

\Large{\bf{\orange{\mathfrak{\dag{\underline{\underline{Solution :}}}}}}} \:†

Solution:

\displaystyle{ \sf{ : \implies \: 2(x + 3) = x + 7}}:⟹2(x+3)=x+7

\displaystyle{ \sf{ : \implies \: (2 \times x )\: + (2 \times 3) = x + 7 }}:⟹(2×x)+(2×3)=x+7

\displaystyle{ \sf{ : \implies \: 2x \: + \: 6 = x + 7 }} \::⟹2x+6=x+7

Taking 6 to right side and x to left.

\displaystyle{ \sf{ : \implies \: 2x - x = 7 - 6 }} \::⟹2x−x=7−6

\displaystyle{ \sf{ : \implies \: x = 1 }} \::⟹x=1

∴ Value of x is 1.

hydrochloride acid
