14(10) + 2, 14x10 is 140 plus 2 = 142
2(7(10) + 1) 7x10 = 70 + 1 = 2(71) = 142
So firstly, add both sides by 6: 
Next, multiply both sides by 4, and your answer will be 
The domain is the entire list of x values, while range would be the same for y. In a graph, we're always going to have a coordinate pair for every point, so more x's than y's or more y's than x's doesn't make sense, there can't be a sole x or y value. Hope this helps!
