what is the value of x to make the statement correct in 5x2-1=4​

Sagot :

Answer:

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.

5ײ-1=4

5ײ=4+1
