x = 5; is an assignment statement that assigns 5 to x.
x = = 5; is a syntax error that fails to compile, missing an expression on the second equals sign.
The second would suggest that x equals the string "=3".
In C: x = 5 always means assign the value of 5 to x; x == 5 always means compare the value of x with 5.
There is no way to know unless you had an equation that gives the relationship between x and y. For example, if y=2x, then when x equals 99 or x equals 100, then the value of y has a difference of 2.
To find the difference between two numbers, subtract them.
There is only one solution: x = 15. Consequently the remainder of the question is nonsense.
The sum of two numbers is 45 and their difference is 5. What are the two numbers? Let's start by calling the two numbers we are looking for x and y. The sum of x and y is 45. In other words, x plus y equals 45 and can be written as equation A: x + y = 45 The difference between x and y is 5. In other words, x minus y equals 5 and can be written as equation B: x - y = 5
Say x is 5 so 5 + 5 = 10 where as 5 times 5 = 25 The difference is "x + x" is a addition and "xx" (x times x) is a multiplication.
x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.
x/5=-4-2 x=(-6)*5 x=-30 the integer is -30
5-x equals 7 = -2
(8 + 4) x 5...
5(x-3)
