this is in a fraction: X = 16/5, decimal form: x = 3.2, and in a mix number: x = 3 1/5
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.
x = 14
Since it's a parallelogram that means x+3= 17.
Subtract 17 by 3 to get x alone that will give you x = 14
x = 14
This quadrilateral is a parallelogram. Due to this, opposite sides are congruent. One side is 17, that means the opposite side is 17. We can write this as the equation
x + 3 = 17.
If we subtract 3 from both sides, we isolate the variable x.
x = 14.
Therefore, x = 14
