The system of linear equations below has the solution (3, 3), where F, G, H, P. Q, and R are non-zero real numbers.
Fr+ Gy=H
Pr+Qy= R
Which system must also have the solution (3,3) ?
3Fx - 3Gy= H
Pr + Qy = R
[ 3Fx + 3Gy = H
13Px +3Qy = R
((F+3P) x + (G+ 3Q) y = H + 3R
Pr+Qy = R
((F+3G) x + (P+3Q) y = H + 3R
Pr+Qy = R
