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.
Step-by-step explanation:
-2x - 4 > 10
Multiply both sides by -1 and reverse the inequality symbol.
2x + 4 < -10
Now subtract both sides by 4.
2x + 4 - 4 < -10 - 4
2x < -14
Divide both sides by 2.
2x/2 < -14/2
x < -7
