Q. What value of d is a solution to this equation?d+8=11Choices:(A)d=3(B)d=4
Identify operation for isolation: Which operation should be used to isolate d?In d+8=11, we should subtract 8 from both sides to isolate d.Subtract 8 from both sides.
Subtract from both sides:d+8−8=11−8Find the value of d.11−8=3d=3
