Simplify the second equation.
1/2y = -x + 1
Multiply both sides by 2
y = -2x + 2
Since both equations equal y you can set them equal to each other.
-2x + 2 = 3x - 1
Solve for X
-5x = -3
x = 3/5
Plug this into one of the equations.
3(3/5) - 1 = y
1.8 - 1 = y
y = .8
(0.6, 0.8)

Answer:
Humans are complex organisms made up of trillions of cells, each with their own structure and function.
Scientists have come a long way in estimating the number of cells in the average human body. Most recent estimates put the number of cells at around 30 trillion. Written out, that’s 30,000,000,000,000!
These cells all work in harmony to carry out all the basic functions necessary for humans to survive. But it’s not just human cells inside your body. Scientists estimate that the number of bacterial cells in the human body likely exceeds the number of human cells.
Lets day the original price of the dvd player was $100,
36% marked down means you pay $64x
64x = $41.60
100x = 100/54 x 41.60 = 4160/64 = #65.00 = original cost
similarly, stereo tuners = 100/78 x 69.42 = 6942/78 = $89 original cost
DVD = 65- 41.60 = $ 23. 40 less
Stereo = 89- 69.42 = $ 19.58 less
Diffrence is $ 3.82
so your answer is the dvd player price was reduced by $3.82 more than the stereo tuner.
