- 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 )

3 (n + 7) = 16
It is a linear equation in one unknown variable, n. Its solution is n = 1
63
n + 16 = 9 n + 16 - 16 = 9 -16 (add 16 to both sides, the equation remains same) n + 0 = -7 n = -7
7 + n = 14 n = 7
You have one linear equation in two unknown variables: A and n. There can be no solution.
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.
It's an equation in 'N' ... about the simplest one you could write.The solution of that equation is: N=0 .
There are infinitely many possibilities. One of these is n+1 = 0
yes because every of mathematics is an equation
3 (n + 7) = 16
7n = 7 divide by 7 on both sides n = 7
To solve the equation 4n + 3 = 31, you will first subtract 3 from both sides of the equation to isolate the term with n. This gives you 4n = 28. Then, you divide both sides of the equation by 4 to solve for n. So, n = 7.
7/8 = 14/nMultiply each side of the equation by 8 :7 = 112/nMultiply each side by 'n' :7n = 112Divide each side by 7:n = 16
It is a linear equation in one unknown variable, n. Its solution is n = 1
