Answer: Choice B. (6, 20)
================================================
Step-by-step explanation:
Based on the answer choices, only choice B has a y coordinate of y = 20. So this must be the answer.
--------
Let's plug in y = 20 to find x
3x+2y = 58
3x+2(20) = 58 .... replace y with 20
3x+40 = 58
3x+40-40 = 58-40 .... subtract 40 from both sides
3x = 18
3x/3 = 18/3 .... dividing both sides by 6
x = 6
We have x = 6 and y = 20 pair up to form the ordered pair (x,y) = (6,20) which confirms B is the correct answer.
