\large\blue\textsf{\textbf{\underline{\underline{Question:-}}}}

Solve the following
\mathrm{2(x+3)=x-4}.


\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

First of all, we can remove the parentheses by multiplying 2 times x and 3:-


\mathrm{2x+6=x-4}

Now that we removed the parentheses, the rest is a piece of cake, as long as we pay attention to the signs, and here's what I mean by that.

Subtract x on both sides:-


\mathrm{2x-x+6=-4}

On simplification, we get


\mathrm{x+6=-4}

Now we subtract 6 on both sides, which results in


\mathrm{x=-4-6}

And finally,


\mathrm{x=-10}

[Verification]

We can substitute -10 for x and see whether or not we end up with a true statement.


\mathrm{2(-10+3)=-10-4}

Perform the operation inside the parentheses first:-


\mathrm{2(-7)=-14}

On simplification, we get


\mathrm{-14=-14}

Since the left-hand side (L.H.S.) is the same as the right-hand side (R.H.S), our solution (x=-10) is correct.

Good luck.
