Question

Which of the following equations has the same solution as m - (-62) = 45?

x + 25 = 8
25 - x = 8
120 - x = 13
120 + x = 13

Answer 1

Since -(-62) can equal 62 by crossing out the negatives (if there's a negative in front of a parenthesis, you can simply multiply the content of the parenthesis by -1) , we get m+62=45. Next, we can subtract 62 from both sides to get m=-17. Plugging x=-17 into each equation, we get that -17+25=8 and that's the right answer
