Answer 3

To solve the inequality 56 + x > 70, follow these steps:

Step 1: Subtract 56 from both sides to isolate the variable x on one side of the inequality: 56 + x - 56 > 70 - 56 x > 14

Step 2: Perform a quick check to verify the solution. Pick a value for x greater than 14 and see if the inequality holds true. Let's choose x = 15:

56 + 15 > 70 71 > 70

Since 71 is indeed greater than 70, the solution is confirmed.

Therefore, the solution to the inequality is x > 14.
