Answer:
bool b = isupper(x);
Step-by-step explanation:
I have written the expression for a char variable x.The isupper(x) will return true if the character x is upper case and false if the character x is lower case.
I have stored the returned value to a bool variable b .So the value of variable b will be true only when the x is in uppercase and false when b is lower case.
The answer is all real numbers for x
because simplifying, you get both sides are equal
Your answer would be x=-10.5
First distribute -2/3 to 3x and -9
-2x+6=15
Then subtract 6 from both sides
-2x=9
Divide both sides by -2
x=-4.5
