Understand Equation: Understand the equation 11=c−8 and identify what we need to solve for, which is the value of c.
Isolate c: To isolate c, we need to get rid of the −8 that is subtracted from it. We can do this by adding 8 to both sides of the equation. This gives us 11+8=c−8+8.
Perform Addition: Perform the addition on both sides of the equation. On the left side, 11+8 equals 19. On the right side, −8+8 equals 0, which leaves us with c on its own. So, we have 19=c.
