Answer 3

To solve the equation 5x + 7 = 0, you need to isolate the variable x. Here's how you can do it step-by-step:

Step 1: Subtract 7 from both sides of the equation to move the constant term to the right side:

5x + 7 - 7 = 0 - 7 5x = -7

Step 2: Divide both sides by 5 to solve for x:

5x / 5 = -7 / 5 x = -7/5

So, the solution to the equation is:

x = -7/5
