37-50002+(x+80000)find avalue of x ?​

Answer»

-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.
