There's nothing there that needs solving, because there's no question there.
Without an "equals" sign ( = ) somewhere, there is no equation, just an expression
whose value depends on the value of 'n'.

To solve for n in the equation 4n + 3 = 19, you first need to isolate the variable n. Start by subtracting 3 from both sides of the equation to get 4n = 16. Then, divide both sides by 4 to find n = 4. Therefore, the solution to the equation is n = 4.
8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
It is 4n
4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7
4n = 3n + 44n - 3n = 3n - 3n + 4n = 4check:4n = 3n + 44(4) =? 3(4) + 416 =? 12 + 416 = 16 True
