Suppose the first equation in a system of two linear equations is 3x−5y=18. The second equation being which of these will cause the system to have an infinite number of solutions? 3x−5y=14 3x−5y=18 3x−7y=14 3x−7y=18

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
