Answer 2

7x - 15 = 13

7x = 15 + 13

7x = 28

x = 4

Answer 3

To solve the equation 7x - 15 = 13, we need to isolate the variable x on one side of the equation. Here's how we can do it step by step:

Step 1: Add 15 to both sides of the equation to eliminate the -15 on the left side: 7x - 15 + 15 = 13 + 15 This simplifies to: 7x = 28

Step 2: Divide both sides of the equation by 7 to solve for x: 7x/7 = 28/7 This simplifies to: x = 4

Therefore, the solution to the equation 7x - 15 = 13 is x = 4.
