Answer: x = -3 and y = 4

Step-by-step explanation:

2x+5y = 14 ....................... equation 1

6x+7y = 10 ....................... equation 2

Using elimination method

multiply equation 1 by (3) and equation 2 by (1)

Then we have:

6x + 15y = 42    .................. equation 3

6x + 7y = 10 ................... equation 4

subtract equation 4 from equation 3 , we have

8y = 32

divide through by 8

y = 4

substitute y = 4 into equation 1 to get the value of x

that is :

2x + 5(4) = 14

2x + 20 = 14

2x = 14 - 20

2x = -6

x = -3

Therefore:

x = -3 and y = 4

What is one-fourth of four sevenths
AlekseyPX
1/4  x 4/7
do the top numbers first. 1 x 4 is 4do bottom numbers next 4 x 7 is 28

that leaves you with 4/28. But you have to reduce.

4/28 = 2/14 = 1/7 (notice I just cut both the top and bottom numbers in half each time I reduced until I couldn't reduce any more).
So, final answer is 1/7
