The system of equations is 2x + 3y =4 Eq 1 3x + 4y = 6 Eq 2 Perform the following row operation on the given system of equations. Eq 1 + 7Eq 2 - new Eq 1 Note that you are not asked to solve the system. Just perform the indicated row operation. Your final answer should include two equations. Give your answer as a comma-separated list if needed. Express numbers in exact form. Use symbolic notation and fractions where needed. Give the equations in terms of y and x.) new system of equations:Perform the indicated row operation on the system of equations. ( 2x + 3y = 4 Eq 1 5x + 4y = 5 Eq 2 Note that you are not asked to solve the system. Just perform the indicated row operations. Eq 2 - Eq 1 - new Eq 2 followed by Eq 1 + 5 Eq 2 - new Eq 1 (Express numbers in exact form. Use symbolic notation and fractions where needed. Give the equations in terms of y and x.) new Eq 2: new Eq 1:A milling company mixes alfalfa, which contains 20% protein, with wheat midds, which contain 15% protein. The goal is to make 1000 pounds of feed that contains 18% protein. How many pounds of each ingredient are in the feed mixture? Suggestion: Make one equation that shows the total pounds of feed and another that shows the total pounds of protein. (Let a represent the number of pounds of alfalfa and w represent the number of pounds of wheat. Give your answers as whole numbers.) a = pounds W = poundsYou have $132000 to invest in two funds. Fund 1 pays an average 3% return, and fund 2 pays an average 6% return but is a riskier investment than fund 1. To obtain maximum average return at an acceptable risk level, your financial advisor suggests you should invest so that the average return is 5%. Using x for the money invested in fund 1 and y for the money invested in fund 2, both in dollars, write a system of two equations in two unknowns that will determine x and y. Suggestion: The first equation should be the total amount invested in terms of x and y. The second equation should be the dollar amount (not percentage) of return in terms of x and y. (Express numbers in exact form. Use symbolic notation and fractions where needed. Give the equations in terms of y and x.) Equation 1: Equation 2: How much should you invest in each fund? (Give your answers as whole numbers.) X = dollars y = dollarsFind the solution of the following system of equations. x + 2y+ 3z = 16 3x + 4y + 6z = 9 7x + 8y + 8z = 15 (Give your answer in the form (*,*,*). Express numbers in exact form. Use symbolic notation and fractions where needed. Enter NO SOLUTION if system cannot be solved. Express x, y, and z in terms of : if system has infinitely many solutions.) ( x, V, Z ) =
