Answer: c
Step-by-step explanation:
Hello!
Let's begin by multiplying all 3 terms by 4, to remove the fraction:
2(r-3) - 8(4) = 50(4)
Then 2r - 6 - 32 = 200. Consolidating the constants on the right side, we get:
2r = 162. Solving for r, we divide both sides by 2, obtaining r = 81 (answer)
Answer:
80 and 90, it is 81.
Step-by-step explanation:
x + y = 3 -------------- i x2
2x - √3y = 5 ---------ii x1
Subtracting eq ii from i
2x + 2y = 6
- 2x - √3y = 5
-------------------------
2+ √3y = 1
y = 1/ 2+√3
= 2- √3y
