Step-by-step solution

To solve the equation 8x=5 -8 - x = -5 , we'll isolate the variable x x by performing algebraic operations:

Step 1: Add 8 to both sides of the equation to eliminate the 8-8:

8x+8=5+8 -8 - x + 8 = -5 + 8

This simplifies to:

x=3 -x = 3

Step 2: To solve for x x , we need to change the sign of x x . Multiply both sides by 1-1:

x=3 x = -3

Therefore, the solution to the equation is 3\boxed{-3}.
