WebTo check, replace y with –25: Example 11 Solve for x. 3 x + 2 = x + 4 Subtract 2 from both sides (which is the same as adding –2). Subtract x from both sides. Note that 3 x – x is the same as 3 x – 1 x. Divide both sides by 2. To check, replace x with 1: Example 12 Solve for y. 5 y + 3 = 2 y + 9 Subtract 3 from both sides. WebTo solve the equation for different variables step-by-step clear any fractions by multiplying both sides of the equation by the LCM of the denominators. Get all the terms with the wanted variable on one side of the equation and all the other terms on the other side.
