Question

9+4n=-59

Answer 1

Solve for n:
4 n+9 = -59
Isolate terms with n to the left hand side.
Subtract 9 from both sides:
4 n+(9-9) = -59-9
Look for two terms that sum to zero.
9-9 = 0:
4 n = -59-9
Evaluate -59-9.
-59-9 = -68:
4 n = -68
Solve for n.
Divide both sides of 4 n = -68 by 4:
(4 n)/4 = (-68)/4
Any nonzero number divided by itself is one.
4/4 = 1:
n = (-68)/4
Reduce (-68)/4 to lowest terms.
The gcd of -68 and 4 is 4, so (-68)/4 = (4 (-17))/(4×1) = 4/4×-17 = -17:
