If it's not what You are looking for type in the equation solver your own equation and let us solve it.

Simplifying 7k + mn = n Solving 7k + mn = n Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-1mn' to each side of the equation. 7k + mn + -1mn = -1mn + n Combine like terms: mn + -1mn = 0 7k + 0 = -1mn + n 7k = -1mn + n Divide each side by '7'. k = -0.1428571429mn + 0.1428571429n Simplifying k = -0.1428571429mn + 0.1428571429n
