Solve by substitution or elimination
1.) -6=3x-6y
4x=4+5y
2.) r+x= -1
2r-3s=6
1. x = (4+5y)/4
-6 = 3x - 6y
Substitute (4+5y)/4 for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.
2. Is there a typo in this part? Correct and use similar process.
