Solve the system of equations by any method. 3m4yl23 = 19 (I) 2m+4y+z=20 (2)' 2m+3y+52=23 (3) Enter the exact answer as an ordered triple, (at, y, z). Hint: There are multiple ways to solve this system of equations. I A strategy is to eliminate one of the variables and end up with 2 equations in 2 variables. I One way to do that is to begin with equation 2 to get 3 = 20 2 :1: 4 y. I Then substitute 2!] 2 a: 4 y for z in equations 1 and 3. I You now have 2 equations (the modied equations 1 and 3) in 2 variables (a: and y}. I Solve this smaller system for a: and y and then use 2: = 20 2 a: 4 y to calculate z
