How to solve an equation with x and y

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.
