Answer 3

To solve the equation 8x - 7 = 5x + 8, you want to isolate the variable x on one side of the equation. Here's the step-by-step process:

Step 1: Get rid of any constants on either side of the equation. To do this, add 7 to both sides of the equation: 8x - 7 + 7 = 5x + 8 + 7 8x = 5x + 15

Step 2: Get all the x terms on one side of the equation. To do this, subtract 5x from both sides of the equation: 8x - 5x = 5x + 15 - 5x 3x = 15

Step 3: Solve for x. Finally, to find the value of x, divide both sides of the equation by 3: 3x / 3 = 15 / 3 x = 5

So the solution to the equation is x = 5.
