X/7- y/5=1 solve for y
Usimov [2.4K]

Answer:

y = 5/7 x -5

Step-by-step explanation:

X/7- y/5=1

Multiply each side by 35 to clear the fractions

35(X/7- y/5) =1*35

5x - 7y = 35

Subtract 5x from each side

5x-5x-7y = -5x+35

-7y = -5x+35

Divide each side by -7

-7y/-7 = -5x/-7 +35/-7

y = 5/7 x -5

If you bought a tv for $350 and you bought it at a 10% discount off what was the original price
blagie [28]
(not sure if I'm right) Using this Formula Part/Whole = %/100

$350/Original Price = 10%/100
cross multiply 
10w = 35,000
divide by 10 on both sides 
W = $3,500 
(seems real high so I'm not sure)
