Answer:

No mistake

Step-by-step explanation:

Given the equation solved by Lian expressed as;

s  + 40 = 68

Lian is to find the value of s from the equation, to do that you will follow the steps below;

Step 1: Substract 40 from both sides of the equation;

s  + 40 - 40 = 68 - 40

Step 2: Solve for s;

s  + 40 - 40 = 68 - 40

s + 0 = 68 - 40

s = 28

Based on the calculation, we can say that Lian made no mistake when solving
