n+19 if considering a normal adding equation

You cannot write an algebraic expression for that, you need an equation. The equation is n - 6 = 4

2*n + 5 = 35

Your equation would be 5(x + 4). In this case it's easiest to work backwards, starting with the "sum of a number and four" part of the problem. This is simply written as x + 4, since we don't know what "a number" is referring to and have to call it x. Then we just need to multiply that answer by 5, so we'd write the equation as 5 * (x + 4) or 5(x + 4). Make sure you have the parentheses, because if not it changes the answer entirely.

You want to create an equation for this. The equation should look like this: x^2 - 2x + 4 = 0 Use the quadratic equation to solve it.
