A privacy-conscious worked example with the original question, step-by-step reasoning, common traps, and similar practice.
Guided solution
To solve for y, we need to isolate it on one side of the equation. We start by distributing the 5, then subtract 20 from both sides, and finally divide by 5 to find the value of y.
This problem involves basic algebraic manipulation, which is suitable for grade-4 students who are beginning to learn about solving equations.
By distributing and then isolating the variable, we find that y equals 3.
