Solving linear equations — Maths Olympiad practice
An equation is a balance. To find x, undo what has been done to it, one step at a time, doing the same thing to both sides. In a multiple-choice paper you can also check each option by putting it back into the equation.
Work it out on paper, then tap the answer you think is right. Stuck? Press “Show me how” to see every step.
