Answer:
rrtrrrfddddddddfffffffddddd
5r + 6s = 53
25r + 3s = 49
Meaning of simultaneous is to solve by elimination
Multiply the equation 2 by -2
-2( 25r + 3s = 49)
-50r – 6s = -98
Then add the two equation to eliminate s, so the resulting equation is:
-45r =-45
r = 1
substitute r = 1 to equation 1
5(1) + 6s = 53
6s = 53 – 5
6s = 48
