Question

Solve the following question: \[x-5=8\].

Answer 1

Hint: In this problem, we have to solve and find the value of x. Here we just have to add or subtract the similar term, on both sides in order to cancel the terms near the unknown variable and to get the value of it. We can first add 5 on both sides in the given equation, we can then cancel similar terms on the left-hand sides and we can add the terms on the right-hand side, where we will get the value of x.

Complete step-by-step solution:
Here we have to find the value of x.
We know that the given equation to be solved is,
\[x-5=8\]
Here we just have to add or subtract the similar term, on both sides in order to cancel the terms near the unknown variable and to get the value of it.
We can first add 5 on both sides in the given equation, we get
\[\Rightarrow x-5+5=8+5\]
We can now cancel similar terms on the left-hand sides and we can add the terms on the right-hand side, we get
\[\Rightarrow x=13\]
Therefore, the value of x is 13.

Note: We should always remember that if we have similar terms with opposite signs, then we cancel them. We should know that if the resulting value is substituted in the given equation, it should satisfy the condition. We can now check for it by substituting 13 in the given equation.
\[\begin{align}
  & \Rightarrow 13-5=8 \\
 & \Rightarrow 8=8 \\
\end{align}\]
Therefore, the resulting answer is correct.
