2x-y=6 and 5x+10y=-10

Mathematics
1 answer:

2x - y = 6
5x + 10y = -10

<span>( 2x - y = 6 ) * 5
</span>10x - 5y = 30

<span>( 5x + 10y = -10 ) * 2
</span>10x + 20y = -20

If we subtract the last 2 equations,
30y = -50
y = -(5/3)

2x - (-5/3) = 6
2x + (5/3) = 6
2x = 6 - (5/3)
2x = (18-5)/3
2x = 13/3
x = 13/6

A television costs $350 before sales tax is applied. The final cost of the television was $378.
lana [24]
To get the answer we can use proportion. We know that 350 its 100% and 378 its 100% + taxes.
350% ------------ 100
378% ------------ x
cross multiply now
350*x=378*100
350x=37800      /:350
x=108 
Now we see that taxes its 8%, because final price its 100% + taxes = 108%
