2r-s=4
(1)12
(2)15
(3)17
(4)20

Answer 1

Answer:

Sorry i just need points

Step-by-step explanation:

Answer 2

Answer:

• (4) s = 20

Step-by-step explanation:

Given system:

• r + 2s = 52
• 2r - s = 4

Eliminate r to solve for s.

To do so, double the first equation and then subtract the second one:

• 2r + 4s = 104
• 2r - s = 4

Subtract

• 4s - (-s) = 104 - 4
• 5s = 100
• s = 100/5
• s = 20

Correct choice is (4) 20
