Answer:

x= 0 , y= 6

Step-by-step explanation:

multiplying 1st equation by 2 and subracting equation 2nd from 1st

14x + 4y = -24

<u>- ( 3x + 4y) = - (-24</u>)

11x = 0

so, x=0

keep x=0 in equation 2nd

3*0 + 4y = -24

y = -24 / 4

so , y = 6

Y = 3x - 1

lubasha [3.4K]

Answer:

no solution.

Step-by-step explanation:
