Note: sqrt means square root, and * means multiply method (overall aim is to make x the subject): multiply both sides by sqrt(5) to get: 15 * sqrt(x) = 6 * 5further expand the right hand side to get: 15 * sqrt(x) = 30divide both sides by 15 to get: sqrt(x) = 2square both sides to find x: x = 4answer: 4
