Answer:
40%
Step-by-step explanation:
just take a number, for example, 1, and do the math.
1 - 30% = 0.7.
1 - 50% = 0.5.
0.7 / 0.5 = 1.4.
thus the answer is 40%.

x = 4
y = 13
x + y = 17
y = 2x + 5
substitute for y:
x + (2x + 5) = 17
reduce:
3x + 5 = 17
subtract 5 from each side:
3x = 12
divide both sides by 3:
y = 2(4) + 5
