Answer 3

To solve the equation 50 - 20 + c = 40, you need to isolate the variable 'c' on one side of the equation. Here's the step-by-step solution:

1. Combine like terms on the left side of the equation: 50 - 20 + c = 30 + c

2. Subtract 30 from both sides of the equation to move the constant term to the right side: 30 + c - 30 = 40 - 30 + c c = 10

So the solution to the equation is c = 10.
