To solve the equation -n = 7, you need to isolate the variable n. To do this, you can multiply both sides of the equation by -1 to get n by itself. By multiplying both sides by -1, you get n = -7. Therefore, the solution to the equation -n = 7 is n = -7.
Well, isn't that a happy little equation we have there! To find the solution, we simply need to think of the negative sign in front of the 'n' as a debt we owe. So, to balance the equation and make it happy again, we can multiply both sides by -1 to get the solution: n = -7. And just like that, we've turned a problem into a lovely solution!
- n = 7
multiply through by, - 1
- 1(- n = 7)
a negative times a negative is positive ( and, of course, a negative time a positive is negative )
n = - 7

- (- 7) = 7
( negative times negative = positive )

You have one linear equation in two unknown variables: A and n. There can be no solution.
How would you get 35 out of 7n equals 245 in algebra?
7n = 245To isolate n, divide both sides of the equation by 7.n = 245 / 7n = 35Check:L.S. = 7nL.S. = 7(35)L.S. = 245R.S. = 245L.S. = R.S.245 = 245The equation is true, so the solution is n = 35.
