What's is the value of x in maths​

Answer»

Step-by-step explanation:

The LETTER "x" is often USED in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "UNKNOWN". In x + 2 = 7, x is a variable, but we can WORK out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol
