What is solution of 8x-2y =1 and -4x+y = 3
Maksim231197 [3]

Answer: it has no solution

Step-by-step explanation:

8x - 2y = 1 ..................... equation 1

-4x + y = 3 ...................... equation 2

solving the system of linear equation by substitution method . From equation 2 , make y the subject of the formula.

y = 3 + 4x .......................... equation 3

substitute equation 3 into equation 1 .

8x - 2(3 + 4x ) = 1

8x - 6 - 8x = 1

8x- 8x - 6 = 1

-6 = 1

this means that the equation has no solution

Is 4/6 greater than 4/7?
dexar [7]
Yes, to make it simpler and easier to tell, you could put both these fractions into decimals or percentages.

4/6 as a decimal would be .66 or 66%
4/7 as a decimal would be .57 or 57%

Hope this helps! :}
