Answer 2

To solve the equation 7x - 9 = 40, follow these steps:

Step 1: Add 9 to both sides of the equation to isolate the term with "x" on one side: 7x - 9 + 9 = 40 + 9

This simplifies to: 7x = 49

Step 2: Divide both sides by 7 to solve for "x": 7x/7 = 49/7

This simplifies to: x = 7

So, the solution to the equation is x = 7.
