x + y = 41, where x and y are unknown integers.
x + y = 41
-- Write down the information given in the question. -- Understand and write down exactly what the question is. -- Write down all the formulas or equations you know that contain the given quantities or the unknown quantity. -- Use what is given and what you know to find what is unknown. The answer to "integers fraction question" is going to depend on what the question is.

The normal way of showing that y is a function of x is to write y = f(x).
2HgO------->2Hg+O2
You can find those by trial and error. You can also write an equation for the three consecutive integers, and solve it. If the first number is "n", the others are "n + 1" and "n + 2". By solving the equation for "n", you get the first of the three numbers.
Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.
Write down any two mathematical expressions, making sure that at least one of them contains an unknown quantity, and write the statement saying that they're equal to each other.
Let x be the first integer. Then the sum of the three consecutive integers is x + (x+1) + (x+2), which equals 3x + 3. We are given that this sum is 43, so we can write the equation 3x + 3 = 43. Solving this equation, we find that x = 13. Therefore, the three consecutive integers are 13, 14, and 15.
Write an equation of 3/8×112
CaCl2 (s) -> Ca+2 (aq) + 2 Cl-1 (aq).
youranswer would be -23x+y=-253 because you add 23x to both sides (to y and itself)
