Answer:
First, subtract 11 from both sides. Then, multiply both sides by −1.
First, add n to both sides. Then, add 20 to both sides.
Step-by-step explanation:
Given equation:
11 - n = -20
Solve for variable n
11 - n = -20
Subtract 11 from both sides
11 - n - 11 = -20 - 11
- n = - 31
Multiply both sides by -1
- n(-1) = - 31(-1)
n = 31
First, subtract 11 from both sides. Then, multiply both sides by −1.
11 - n = -20
11 -n +n = -20 + n
11 = -20 + n
11 + 20 = -20 + n +20
31 = n
First, add n to both sides. Then, add 20 to both sides.
First, subtract n from both sides. Then, multiply both sides by −20.
First, add n to both sides. Then, subtract 11 from both sides.
11 - n = -20
11 - n +n = -20 + n
11 = -20 + n
11 - 11 = -20 + n -11

First, subtract 11 from both sides. Then, multiply both sides by −1.
First, add n to both sides. Then, subtract 20 from both sides.
11 - n = -20
11 - n + n = -20 + n
11 = -20 + n
11 - 20 = -20 + n - 20
9 = n - 40
