Webfor x and y. 2. Solve the problem. To solve the problem, we solve the system of equations. We can multiply the second equation by 10 to get rid of the decimal point. This gives us. 15 x + 30 y = 210. Now we can divide this equation by 5 to make the numbers smaller and easier, which gives us. 3 x + 6 y = 42. WebSolve: −200P 2 + 92,000P − 8,400,000 = 0. Step 1 Divide all terms by -200. P 2 – 460P + 42000 = 0. Step 2 Move the number term to the right side of the equation: P 2 – 460P = -42000. Step 3 Complete the square on the left side of the equation and balance this by adding the same number to the right side of the equation:
