A tool company manufactures pliers and scissors. In one hour the company uses 140 units of steel and 290 units of aluminum. Each pair of scissors requires 1 unit of steel and 3 units of aluminum. Each pair of pliers contains 2 units of steel and 4 units of aluminum.
(a) Write a system of equations to find how many pairs of scissors and pliers the tool company can make in one hour.
(b) Find the number of pairs of scissors and pliers they can make.To solve a system using a matrix equation (with a little help from me):1. Determine which unknown will be x and y
x = # scissors, y = # pl
