Equation; y=27x+405Step 1: Flip the equation. 27x + 405 = y Step 2: Subtract 405 from both sides. 27x + 405 = y

-405 - 405 27x = y-405 Step 3: Divide everything by 27. 27x = y - 405

27 27 27 - - - dividing by 27 will isolate x which is the goal of solving the equation---

x = 127 y - 15

Answer: x = 127 y - 15
