Answer/ Explanation in detail:
A variable in an equation is a symbol that serves as a placeholder for varying expressions or quantities and is often used to represent an arbitrary part of a constant. Like x & y a variable
The x in the equation 6x = 24 stands for a variable.
You solve x in question 2, 6x = 24
6x = 24
Step 1: Divide both sides by 6
6x/6 = 24/6
x=4
To check if the answer is right you substitute 4 for the x.
6x=24
6(4)= 24
24=24
Both sides are equal so the answer, x=4, is correct
