Question

x = 23 is a solution for the equation x/2 = 10 true or false

Answer 1

False

Here, we want to check if x = 23 is a solution for the equation

Firstly, we need to understand that what we have is a linear equation, an equation in which the highest power of the variable is 1. For this type of equations, what we expect is a single solution.

Thus;

$\begin{gathered} \frac{x}{2}\text{ = 10} \\ \\ x\text{ = 2 }\times\text{ 10} \\ \\ x\text{ = 20} \end{gathered}$

Since x = 20 is the only possible solution, then x = 23 as a solution must be incorrect and false
