Assuming you are asking
does -2x+y=6 and y-2x=4 have a solution
look at them
rewrite first equation by switching x and y
y-2x=6 and
y-2x=4
false since they are same values
there is no solution
these 2 lines are paralell
NO SOLUTION
Answer:
Below
Step-by-step explanation:
(2x/x+3) + (x+3/x-5)
Transform: 2x(x-5) + (x+3)^2 / (x+3)(x-5)
Remove brackets and expand : 2x^2 - 10x + x^2 + 6x + 9 / x^2 - 5x + 3x - 15
Collect like terms : 3x^2 - 4x + 9 / x^2 - 2x - 15
Final answer: 3x^2 - 4x + 9 / x^2 - 2x - 15
Answer:
$65.80
Step-by-step explanation:
Divide 26.32 by 8 to find how much is in one gallon.
26.32÷8=3.29
So it's 3.29 per gallon.

20×3.29= 65.8
So he would spend $65.80
