2r+3s=29 --- times 3 ---> 6r + 9s = 87
3r+2s=16 --- times 2 ---> 6r + 4s = 32
subtract these last two equations
5s = 55
s = 11
now sub that back into 2r + 3s = 29 to find the r
Solve by elimination method 2r+3s=29 and 3r+2s=16
2 answers
2r+3s = 29
3r+2s = 16
Multiply Eq1 by 3 and Eq2 by 2; then subtract Eq2 from Eq1:
6r+9s = 87
6r+4s = 32
diff. 5s = 55
S = 11.
In Eq1, replace S with 11 and solve for r:
2r+3*11 = 29.
3r+2s = 16
