Find the solution of this system of equations -2x+8y=14 and -2x-2y=-26

Note that both equations contain -2x so if we subtract them this will disappear.

-2x + 8y = 14

-2x - 2y = -26       Subtract:-

0  + 10y = 40

y = 4

Substitute fro y in the first equation:-

-2x + 8(4) = 14

-2x = 14 - 32 = -18

x = 9

Answer x = 9   y = 4

77/306 or around 25.2%

Step-by-step explanation:

section 1/total * section 2/(total-1) since there is no replacement

just solve and you get 77/306
