Answer 3

To solve the equation, we need to isolate the variable "b" on one side of the equation. Let's go step by step:

Given equation: 560 + b = 980 - 140

Step 1: Combine the constants on the right side of the equation: 980 - 140 = 840

So the equation becomes: 560 + b = 840

Step 2: Isolate the variable "b" on one side by subtracting 560 from both sides of the equation: 560 + b - 560 = 840 - 560 b = 280

The solution to the equation is b = 280.
