Question

How do you solve $2x+7=x-3$?

Answer 1

Hint: Try to separate the variables and constants. Keep all the terms containing the variable ‘x’ on the left side of the equation and all the constant terms on the right side of the equation. Do the necessary calculation to get the value of ‘x’.

Complete step by step solution:
Solving the equation means, we have to find the value of ‘x’, for which the equation gets satisfied.
The equation we have $2x+7=x-3$
We have to keep all the terms containing ‘x’ on the left side of the equation and all constant terms on the right side.
So bringing ‘x’ to the left side of the equation and 7 to the right side of the equation, we get
$\begin{align}
  & \Rightarrow 2x-x=-3-7 \\
 & \Rightarrow x=-10 \\
\end{align}$
Hence the solution of $2x+7=x-3$ is $x=-10$.
This is the required solution of the given question.

Note: The constant terms and the terms containing ‘x’ should be separated. Constants should be kept on the right side of the equation and the terms containing ‘x’ on the right side of the equation. Necessary calculation and simplification should be done to get the value of ‘x’.
