1.consider the system of equations. x-5y=2 3x-10y=11 (a) jamar rewrote the first equation as –2x + 10y = –4. what justification did he have for doing this? (b)jamar combined the equation in part (a) with the second equation in the system to get x = 7. explain jamar’s reasoning. (c) what is the solution of the system? (d) how do you know, without graphing, that the graph of 4x – 15y = 13 passes through the point whose coordinates are the solution of the system?
