Answer:

You got it correct :)

Step-by-step explanation:

$\frac{28}{y} =\frac{40}{100}$

y × 40 = 100 × 28

40y = 2800

40y ÷ 40 = 2800 ÷ 40

y = 70

Tell whether the system has one solution, infinitely many solutions, or no solution.

X=-7y+34
x+7y=32

To begin with make the two problems the same kind of problem. By adding 7y on both sides for the first problem.
x+7y=34
x+7y=32

So the correct answer would be no solution because it's the same problem and it can't equal to different answers.
