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

Answer:
z ≤ 17
Step-by-step explanation:
Step 1: Subtract 37 from both sides.
0.1 × 60,000 = 10x. Combine the terms on the left side of the equation.
6,000 = 10x. Divide each side by 10.
600 = x
