5(n+10)=5n+10n 5n+10n=5n+10n I subtract 5n from both sides 10n=10n Only one side is supposed to have the variable which is n, so the equation has no solution.
Although x ² and x both have the variable x, you can’t add them together. So x + x + x + x is 4x and we just leave x ² the same. So the simplified expression is x ² + 4x. I hope this helped!!
