Answer:
n=5
Step-by-step explanation:
Simplifying 7n + -4 = 31
Reorder the terms: -4 + 7n = 31
Solving -4 + 7n = 31 Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right. Add '4' to each side of the equation.
-4 + 4 + 7n = 31 + 4
Combine like terms: -4 + 4 = 0 0 + 7n = 31 + 4 7n = 31 + 4 Combine like terms: 31 + 4 = 35 7n = 35
Divide each side by '7'. n = 5
Simplifying n = 5
