Question

3 x minus y + 7/ 11 - 8 is equal to 0 2 Y + x+4/7 =0​

Answer 1

answer

X=1354/77 Y=-699/593

Step-by-step

2Y+X+4/7=0

X= -(2Y+4/7)__(!)

now,

3X-Y+7/11-8=0

3X-Y=8-7/11

-3(2Y+4/7) -Y=81/11

-6Y-12/7-Y=81/11

-7Y=81/11+12/7

-Y=(699/77)*7

Y=-699/593

from___(!)

X=-(2*699/77+4/7)

X=1354/77
