In the given expression:
(2x + 4) = 12
x is called a variable, for which its value is unknown, but it can be solved by equating the given expression to 0. A variable can be any letter, and it sometimes can represent a measurement in a function such as t = time.
To find the value of x in the given expression, we will equate the expression to 0
2x + 4 =12
2x = 12 - 4
2x = 8
x = 4
